Consider the product P = (-1) x (-2) x (-3) x ... x (-10), the product of the first ten negative integers. Without computing the full value, determine only the SIGN of P. Choose the correct sign.

Question

Accepted Answer

Positive, because there are 10 (an even number of) negative factors. The sign of a product depends on the number of negative factors. There are 10 negative factors, and 10 is even, so the product is positive.

Consider the product $P = (- 1) \times (- 2) \times (- 3) x ... x$ (-10), the product of the first ten negative integers.
Without computing the full value, determine only the SIGN of $P$ .
