alec said that –75 – + 21 equals –54. is alec's answer reasonable? a. yes, because if you start at –75 on a number line, and then move 21 spaces to the right, you will get –54. b. no, because if you start at –75 on a number line, and then move 21 spaces to the left, you will get –96. c. no, 75 – 21 equals 54. because you are subtracting a positive integer, the answer will also be a positive integer. the answer should be +54.
