AThe value 2
BThe value -2
CThe value -12
DThe value 12
Answer & Solution
Correct answer: B. The value -2
1. Rewrite the subtraction using the subtraction property: -7 - (-5) becomes -7 + 5.
2. Adding a number with a different sign means subtracting the smaller absolute value from the larger: 7 minus 5 is 2.
3. Since -7 has the larger absolute value, the result keeps the negative sign, giving -2.
