According to the subtraction property, how can a - b always be rewritten?
AAs -a + b
BAs b + (-a)
CAs -a - b
DAs a + (-b)
Answer & Solution
Correct answer: D. As a + (-b)
1. The subtraction property gives a general rule for turning any subtraction into addition.
2. It states that a minus b equals a plus the opposite of b.
3. So subtracting a number is always the same as adding that number's opposite.
