(i) The product (–9) × (–5) × (– 6)×(–3) is positive whereas the product (–9) × ( –5) × 6 × (–3) is negative. Why?

Answers (1)

We know,

If the number of negative integers in a product is even, then the product is a positive integer and if the number of negative integers in a product is odd, then the product is a negative integer.

Hence, the product (-9) \times (-5) \times (- 6)\times(-3) is positive whereas the product (-9) \times (-5) \times 6\times(-3) is negative
