Flashcard 4 - Mathematics Flashcard Set for the TABE Test

The product of numbers with opposite signs will always be negative. The product of numbers with the same signs will always be positive.

If the numbers have opposite signs: \((-3) \cdot 13 = -39\) and \(3 \cdot (-13) = -39\)
If both numbers have negative signs: \((-3) \cdot (-13) = 39\)
If both numbers have positive signs: \(3 \cdot 13 = 39\)
