Error Analysis Marcel and Naryam do their math homework together. When they find 7-(-6), they get different answers. Marcel claim
Naryam claims the difference is - 13. Who is correct? What error likely led to the incorrect difference?
Marcel is correct.
What error likely led to the incorrect difference?
O A. Subtracting the first integer from the second integer
O B. Subtracting the opposite of the second integer from the first integer
O C. Subtracting the first integer from the opposite of the second integer
O D. Adding the opposite of the second integer to the first integer

Answer 1

A

Explanation:

Subtracting the first integer (7) from the second one (-6) is equal to -13 (-6 - 7 = -13 is the correct order to get -13 as an answer, not 7 - (-6)). The correct answer for 7 - (-6) is 13, because two negative signs turn into a positive, therefore adding up to 13.
