Let’s see which of the following options will result into the given expression:
Option 1:
- (- 7 + 8): distribute the negative sign into the parenthesis:
A negative integer multiplied with another negative integer results into a positive integer. While a negative integer multiplied with a positive integer results into a negative integer.
Therefore: - (- 7 + 8) = 7 - 8 (matches the given expression).
Subtracting 8 from 7 will result to - 1. 7 - 8 = - 1
Option 2:
0 — 7 + ( - 8) → distribute the positive into (-8) results to -8.
Therefore: 0 — 7 + ( - 8) = - 7 - 8 = - 15
Option 3:
07 + (-8) → 07 and 7 are the same. You must also distribute the positive into (-8) results to -8.
Therefore: 07 + (-8) = 7 - 8 (matches the given expression).
7 - 8 = -1
Option 4:
- 7 + 8 (These integers have different signs). Adding them together:
- 7 + 8 = 1
Out of the four options, options 1 and 3 matches the given subtraction expression, 7 — 8.
Therefore, the correct answers are: - (-7 + 8) and 07 + (-8)
