Question

Write the subtraction as an addition: (-27)-(-27)

Answer 1

Remember that when you subtract a negative number, you are really just adding the number. This is represented as:

$a - (- b) = a + b$

Thus, we can simplify

$(-27) - (-27)$,

as

$-27 + 27$

Our answer is -27 + 27.

Answer 2

Remember two negatives gives you a positive. So:

-27 - (-27)    =   -27 + 27

Hope this helps you!
