Question

- 7 -4 =
4 - ( - 7 ) =

Answer 1

- 7 - 4 = -11

Adding two negative numbers is like moving two steps to the left on a number line. -7 is 7 steps to the left of 0, and -4 is 4 steps to the left of 0. So, -7 - 4 is 11 steps to the left of 0, which is -11.

4 - ( - 7 ) = 11

Subtracting a negative number is like adding a positive number. So, 4 - ( - 7 ) is the same as 4 + 7, which is 11.

Answer 2

Integers

Evaluate both of the above.

-7 - 4 = -11

4 - (-7) = 4 + 7 = 11
