Studdy Solution

STEP 1

Assumptions1. We are dealing with real numbers. . The operation of subtraction is defined as the addition of the additive inverse.

STEP 2

The operation of subtraction is defined as the addition of the additive inverse. Therefore, we can rewrite the expression as follows−6−(−15)=−6+(−(−15))-6-(-15) = -6 + (-(-15))

STEP 3

The negative of a negative number is a positive number. Therefore, we can simplify the expression as follows−6+(−(−15))=−6+15-6 + (-(-15)) = -6 +15

STEP 4

Now, we can perform the addition operation.
−6+15=9-6 +15 =9So, the expression −6−(−15)-6-(-15) evaluates to 99.
