What is the sign of the product?

(0.3)(–9.2)(–8.1)(4.2)(–0.8)

A.
positive

B.
negative

Answer 1

Negative

Answer 2

Well if you have (-1)(-1) that's 1 right? So if you have (-1)(-1)(-1) that's the same as 1*(-1) which is -1. The point is, if there's an even number of (-1)'s then you know it's positive. If odd it's negative.
