Answer:
positive; negative
Explanation:
If a student is multiplying two positive numbers, the answer will always be positive.
EX: 3 x 4 = 12
The same applies for two negatives. If two negatives are multiplied it will make a positive answer. This is where the phrase "two negatives make a positive" come from.
EX: -3 x -4 = 12
However, if one number is positive and one is negative, then the answer will always be negative.
EX 1: -3 x 4 = -12
EX 2: 3 x -4 = -12
