Absolute Value…Hint, Hint!
September28
On the number line below, the numbers m and n are the same distance from 0. Which of the following equations is correct:
m + n = 0
m – n = 0
m = n
m/n = 1
PLEASE READ THIS!!!! Don’t just select an answer. PROVE IT by using an example (or two)!
10-8=2. 10+8=18. I have prove my answer by addng & subtracted and got answers bigger than 1.
Your answer does not make sense Eric!
i think the answer is the 3rd one. i think this because if you plugged some numbers in like 5 and 5.m =5 and n=5.so they are an even amount of spaces away.
I think that the first eqaution is true because
i pluged in -3 for n and 3 for m added them and it acually
fit perfectly and did the same with -8 and 8 just to make sure that i was right.
m+n=0 so i had to put the oppsite of a number it will be 8/-8 So i put my 8/-8 in m/n
ex1 8+-8=0
the 2sd one becuase you use same change change it will = 16
well i think that it would be m+n= because if u look on the number line just because the n comes firt doesn’t mean you need to do that exact letter or number first. How do you know wht numbers to use MRS.Ellison??? dont we need numbers to do the problems. I also think that you can do m-n=because it doesn’t say hat numbers to use so i am trying to figuar this out nd when i add 8+6=14 and when i subtract 8-6=2 the answers are 12 numbers away from each other
M=8
N=6
Oh no! Who does this belong to?
It going to be m+n=0 here are some example 4+(-4) 7+-7=0 and that’s some example.
The answer is m+n=0.
Example: if m=20 then n must equal -20 because -20 is the same amount away from 0 as 20 is and 20 (m) + -20(n) = 0.
Example: if m=5 then n must equal -5 beacuse they are both 5 places away from 0, so 5(m) + -5(n)=0.
M/n=1
Why???? Where is your proof Brandon????
the answer to this is m+n because on the number line the are the only ones that are the same distance apart
The equation m-n=0 is correct; here is why…. on a number line if n=-5 and m=5; the absolute value of -5 is 5 and the absolute value of 5 is 5 so 5-5=0. Another example is: n=-2 and m=2 so the absolute values of each number subtracted is 2-2=0.
Good start Kateena! m-n is not is absolute value marks so should you use absolute value to solve the problem???
M – N =0 is correct because you are subtrating both answers from the positive side and negative side so it would be in the middle nd be 0.
EXAMPLE:
T= -6 L= 6
-6-6= 0
t is m+n=0 because when you add a positive and negative together they cancel each other out for example
2+-2=0
15+-15=0
t is m+n=0 because when you add a positive and negative together they cancel each other out for example
2+-2=0
15+-15=0
20000+-20000=0
if m and n are in the same distance, we have to select one of the answer the answer are “m+n=0,m-n=0,m-n,m/n=1 I think the correct answer is m-n=0 because if m-n are in the same distance it will be 0.
(ex: -5 -5=0 or -10-10 will equal 0)
hi miss ellison it is turie my answer is m=n because there are the equal distance appart like
t———-0———-r
arnt the same apart
Thanks Turie. If they are on opposite sides of 0, can they equal each other? Are they the same number?
m-n=0 because m and n are the same distance away it will be like m=1 and n=-1 1+-1=0 also m=24139 n has to be -24139 and it will equal 0.
Kai, Your answer choice and your examples don’t match!
m-n is the correct equation because if m and n are the same distance apart which would mean that they would be the same number number of space apart from zero example m=4 and n=4 they are the same distance from zero so if you subtracted one from the other it would equal zero that is how i solved this problem
Good start Rachel! If m=4 and n=4 they would be on the same side of 0…in fact, they would be exactly the same point! Does this change your thinking at all?
m-n is the correct eqaution because if m and n are the same distance apart which would mean that they would be the same number of space apart from 0 so it would be like m=3 and n=3 because they are the same distance from 0 so if you subtracted one from the other it would be 0
Good start Jadyn! If m=3 and n=3 then they would both be on the same side of 0…in fact, they would be exactly the same point! Does this change your thinking at all?
I think it would be m+n=0. Because if m=1 and n=-1 than 1+-1=0.
ok, so I think the correct answer is A. witch is m + n = 0. I think this because what if the numbers are negative five and positive five for example: m equals negative 5 and n equals positive 5, or m equals negative 7 and n equals positive 7, or m equals negative 4 and n equals positive 4. The possible examples are endless. this is why I think the answer is A. (: =-).
i say the answer to m is 0, and the answer to n is 0. 0+0=0, 0-0=0, 0=0, and the tricky part is 0/0. there is actually 2 answers to 0/0. the first being, well, 0. because anything divided by 0 is 0. but im not using that answer. the second choice is 1, because anything divided by itself is 1. so 0/0=1.
I am not sure what your answer is Julian!
my answer would be m + n = 0 here are some examples that prove my thinking.
-5+5 =0 i got a zero because they are both the same distance away from each other and when you add a negative with a positive you will get zero pairs and it will leave you with nothing for this one.
-77+77=0 they are both the same distance away from each other no matter how far they are, and when you add a positive with a negative you will get some zero pairs and in this case they are all zero pairs so it leaves me with nothing so it is zero
m=n because in the number líne above m and n are the same distance. Like for example If i have a number líne and on the left side i have -27 and i also have 27 on the Right side it would be the same distance.
Good start Susana! M=n means that m and n are exactly the same. Are -27 and 27 exactly the same?
The answer is m=n.
Example 1: -3=3
Example 2: j=k
In your Example 1, is -3 the same as 3?
My answer is m=n because there the same distance from zero and not one id farther from zero than the other.
Good start Zac! Did you use any numbers to help you check your thinking?
m+n=0 because say m=-2 and n=2 and if you add those numbers it will equal 0 or l-2+2l=0
oh yea, n will be a negative number because it is to the left of zero. (n=-2)
M and n are “KISSING COUSINS” . If they are in the same distance away from 0 on the number line, they r kissing cousins. If added, they r 0 pairs.
For example. N+M=?
if N=-6 and. M=6
-6+6= 0…
so the answer is m+n=0.
The following equation is correct:
m+n=0
If m=2 and If n=-2, then 2+(-2)=0
If m=5 and If n=-5 then 5+(-5)=0
The following equation that is correct is m/n= because each variable is 1 number apart from zero. Also, even though n is -1 away from 0 it still is 1 away.
Good start Rheon! m/n means m divided by n…with that knowledge, is your reasoning still the same?
M +n=0
Would be the true equation
For example if n=-2 and m=2 then 2+(-2)=0
If n=-1/2 and m=1/2 then 1/2+(-1/2)=0
m+n=0 because if you plug in the numbers 8+(-8)=0
4+(-4)=0
M-N=0
|-5|-|5|=0
M N
|43|-|-43|=0
M N

I like how you used numbers to help you make sense of the variables Skylar! Remember that when subtracting, if I can not take away what I have then I end up with more than I started with! If I have -5 – 5, I do not have 5 positives to take away so I am going to end up with more negatives than I started with!
My answer is m+n=0.
How I got this was I replaced m to 5 and n to -5. Once I did this I did all of the problems with the numbers 5 and -5. The one equation that was right was the first one.
Example:
m+n=0
5+-5=0
+++++
– – – – –
That’s how I got my answer that m+n=0.
The equation m+n=0 is the answer. I got this answer because m is going to be a negative since its to the left of zero in the number line. And n is a positive since its to the right of zero. What I did is put a number to fill in for m and n. for m I put -1 and n I put 1 then I added the two numbers and got zero so m+n=0 is the answer.
The answer is: m+n=0
Examples: 2+(-2), 10+(-10)
m-n=0
Eliano, Where is your proof?????
m = n. Because when your doing absolute value your answer will always be positive. Even though (n) is on the negative number side, it’s going to be positive. Absolute value means the distance from zero. My example is
m= 2 and n=-2……..m=| 2 | and n= | -2 |…..(everything ends up positive when doing absolute value!) so in the end it will end up to be m=2 and n=2
So my answer to this blog is m=n
m+n would be the correct equation because if they are the same distance from 0, then if they are added by each other you would have to cancel zero pairs and your answer would be 0. Example 1: -9+9=0 Example 2: -23+23=0
M equals N.
When your doing absolute value everything is going to be positive. Absolute value means the distance from 0. So even though (n) is on the negative number side of your number line, it’s still going to be positive.
My example is
M equals 4, n equals -4
M equals | 4 |, n equals |-4|
(When using absolute value your answer is positive)
So it ends up to be M equals 4, n equals 4
So my answer to this blog is (m) equals (n).
I chose m-n=0 because if knowing that the problem is equal distance from zero tells you if you take away what you have you will have zero.
Good start Madison! Did you use any numbers to verify your thinking?
The correct equation is m + n = 0.
Let’s say m = 4, which would make n = -4. 4 + (-4) = 0.
If m = 7.2, n = -7.2. 7.2 + -7.2 = 0 also.
With any numbers, m + n = 0.
m+n=0 is correct because if it was 2+(-2) it would equal 0 if you do the math.
The correct one is m + n=0
examples:
m=5,n=-5 5 + -5=0
m=2,n=-2 2+-2=0
The numbers have different signs so the cancel each other out.
The equation m+n=0 is correct. If m and n are the same distance away from zero, the numbers are going to be the same except n is going to be negative and m is going to be positive. For example, lets say that m is equal to 3. Since both m and n are the same distance away from 0, then n will be equal to -3. Then we plug the numbers into the equation. 3+(-3)=0. The equation works.
If you plug the numbers in to the other equations, it won’t work. For example, we plug the numbers in to the equation m-n=0. 3-(-3) does not equal 0. It equals 6. If you plug the numbers into the equation m=n, it doesn’t work out either. 3 is not equal to -3. Finally, if you plug the numbers in to the equation m/n=1, it won’t work either. 3/-3 does not equal 1. It equals -1.
——————————————————————————–
Example 1: m=8, n=-8
Equation: m+n=0
8+(-8)=0
The equation works.
Equation: m-n=0
8-(-8)=16
The equation does not work. The equation is equal to 16, not 0.
Equation: m=n
8=-8
The equation does not work. 8 is not equal to -8.
Equation: m/n=1
8/-8=-1
The equation does not work. The equation is equal to -1, not 1.
Juliana, You do an AMAZING job of explaining and showing your work! Keep up the great work!!!!
The equation m-n=0 is correct. I tried (-2)-2 and got 0. Then I tried the equation (-21)-21 and got 0. The answer is the absolute value of both integers.
Good job using numbers instead of the variables to help make sense of the problem Citlally! Remember that when you are subtracting, if you can not take away what you have then you are building more of what you started with…-2 – 2: since you do not have 2 positives to take away, you will end up with more negatives in your answer!
The answer m+n=0 is the correct answer because if there the same distance from they have to be the same number but with a different sign. So let’s say they are n=-1 and m=1 using the integers any positive that is being added with a negative will end up smaller than it was before making the problem 1-1 which equals 0.
How u do this problem is m+n=0 , m-n=0 ,n=m , n/m=1 and what u have to do to solve this problem is 0+0=0, 0-0=0 ,0=0,0/1=0 and that’s what u do when u have values to slove.
I am unclear as to what your answer is Alesha.
The first thing I did was that I made my 2 examples. The first example was that I 3+ (-3). The first thing that I noticed was that there is a + and a – in my mind it’s + multiply – which equals a -. So my answer is 3-3= 0. My second example is 10-(10-) and my answer is 0. The answer is m + n= 0 because the same number on the positive side is the same on the negative side so it will equal zero
The anser to this problem is m + n = 0.
An example to this problem is m+n=0 or 100 +(-100) =0
Another example is m + n = 0 or 335 + (-335) = 0
M-n would show what the distances from 0. For example 8-8=0, 1234-1234=0, it is like and absolute value, m and n have to be the exact same and when you subtract them, the answer should be 0.
I like how you plugged in numbers for m and n to help you make sense of the problem Josias! If m=8 and n=8 or m=1234 and n=1234, wouldn’t they be on the same side of zero (or exactly the same point)?
m=n, because they are the same distance from 0 just like how 1 and -1 are equal distance from 0 so 1=-1.
I like your example using 1 and -1 Dylan! If m was 1 and n was -1 would m=n?
m+n=o because the answer states that there are a m and a o so i thought it would be that answer
I chose the first one because if -1=n and 1=m and if you add -1+1 you get 0
the correct equation would be m+n because they are the same distance away from zero. exsept one would be negitave and one would be positive. an example would be m equals 6. but because m and n are the same distance from zero then N would just be -6. all thats left is checking it so you put the numbers into the equation 6+(-6)=0. the problem is correct!
I think that right answers are m/n=1,n-m=0,m=n
Examples: 4/4=1,4-4=0,4=4
i picked 1 and -1 because if you add those you get 0
Since Mrs.Ellison said M and N are the same distance from 0, M+N=0
is the only equation that is true.
Ex. 1: -11+11=0
Ex. 2: -1,000+1,000=0
SamanthaB
All the equations are correct except for the second one because if m-n= a postive minus a negative,the two negatives equal a positive so the it wouldnt be zero because I plugged in 1 and -1for m and n and 1–1=2 not 0 so that is not true but all the other ones are true
m = n is the answer because when your doing absolute value your answer will always be positive. Even though n is on the negative number side on the number line it is going to be positive! Absolute value means the distance from zero. An example is…
m= 3 and n=-3… m= 3 and n= -3 … Everything will end up positive everything ends up positive when doing absolute value! so in the end it will end up to be m=3 and n=3
That concludes my answer and work for m=n .
The equation m+n=0 is correct. If m and n are the same distance away from zero, the numbers are going to be the same except n is going to be negative and m is going to be positive. For example, lets say that m is equal to 3. Since both m and n are the same distance away from 0, then n will be equal to -3. Then we plug the numbers into the equation. 3+(-3)=0. The equation works.
i pick the frist one because when you get m+o=n you will get m
I think the first one is right becaswv if -3 +3 that = 0 and if we do the same with an other one like -1and 1 that will still get zero
It is going to be m+n=0 here are some examples 6+(-6) and 8+(-8) and that’s some examples.
M-N is the correct equation because it is like 5-5=0 it is the opposite
i got 5.40
and also the numbers were lined up wrong and the decimal was in the wrong place
How do you know the numbers were in the wrong place Dustin?
M-N is correct because its like 5-5=0 and its like the opposite
m+n=0 is the answer because when you add a number on different sides if the number you get that answer.
– ‘M’&’N’ are kissing cousins! haha. . okay back to the problem.
– They are kissing cousins that means they are both the same amount from zero.
– When added, they are 0 pairs.
– Example : N+M=?
N=(-8) & M=8
-8+8=0
– So the answer is M+N=0.
m+n=0 because if both variables are the same distance and n= a negtivte and m= a positive. so a negative plus a positive = 0 if they’re the sam distance apart.
m equals n
oh no! who does this post belong to?
m+n=0 because say m=-2 and n=2 and if you add those numbers it will equal 0 or 1-2+2l=0 and it will be a negative number because it is to the left of the zero.
