Question

Which expressions are equivalent to subtracting a negative? (Select all that apply.)


a - (-b)


adding the opposite of a negative


a+ b


a x b


a - b

Answer 1

Correct choices:
- a - (-b)
- adding the opposite of a negative
- a + b

Reason: subtracting a negative, a - (-b), is the same as adding the opposite of -b (which is +b), so a - (-b) = a + b. "a × b" and "a - b" are not equivalent.
