When adding two integers with different signs, how is the sum found?
AAdd the two absolute values and keep a positive sign
BAdd the two absolute values and keep a negative sign
CMultiply the two absolute values together instead
DSubtract the smaller absolute value from the larger one
Answer & Solution
Correct answer: D. Subtract the smaller absolute value from the larger one
1. Different-signed integers are modeled with counters of two different colors.
2. Pairing opposite colors forms neutral pairs worth zero, which are removed.
3. What remains is the difference between the two absolute values, carrying the sign of whichever number was larger.
