Sandy evaluated the expression below.

(negative 2) cubed (6 minus 3) minus 5 (2 + 3) = (negative 2) cubed (3) minus 5 (5) = 8 (3) minus 25 = 24 minus 25 = negative 1

What was Sandy’s error? Sandy should have evaluated (negative 2) cubed as –8.

Sandy should have not multiplied 5 and 5.

Sandy did not add 2 and 3 correctly.

Sandy should have not subtracted 3 from 6 first.
