Example Question #61 : High School Math
What is the difference between 8 and -2?
-10
4
10
6
-6

Since we want to find the difference between 8 and -2, we want to subtract -2 from 8. Since subtracting is equivalent to adding the same number with the opposite sign, we have the below:
Example Question #1 : How To Add And Subtract Integers In Pre Algebra
Find the difference.
We are subtracting here, so it is important to remember that subtracting is really just adding the same number with opposite sign. Thus we can think of the problem as the following:
Example Question #2 : How To Add And Subtract Integers In Pre Algebra
What is 
Recall that subtracting integers is equivalent to adding the inverse. The inverse of a negative number is the positive number with the same magnitude.
Thus, our problem is equivalent to 
Example Question #3 : How To Add And Subtract Integers In Pre Algebra
Evaluate the following expression:
Recall that subtracting is equivalent to adding the inverse:
The inverse of a negative number is a positive number:
Example Question #1 : How To Add And Subtract Integers In Pre Algebra
What is:
Recall the placement of numbers on the number line. 
When we add these spaces we end up going 
Example Question #4 : How To Add And Subtract Integers In Pre Algebra
What is 
Recall that subtracting a negative number is equivalent to adding the opposite. Thus,
Example Question #5 : How To Add And Subtract Integers In Pre Algebra
