Question

1. If a and b are any two real numbers, explain how you calculate the difference a – b. Be sure to include the following in your explanation:
a. A description of the relationship between addition and subtraction
b. How you can use a number line to help with the calculation
c. How you can determine the sign of the result

Answer 1

If a and b are real numbers, a−b is the same as a+(−b), where −b is the opposite of b.
consider the number line
-1 0 1 2 3 4 5 6
we now use the above number line to illustrate that the subtraction 5−2 produces 3, that is, 5−2=3
We begin at 0, the origin. I DONT KNOW IF THIS HELP OR NOT?
