Question

What is the sign of -9 times (0/-3)

Answer 1

no sign

Explanation:

The value of the product is ...

`-9*(0)/(-3)=(-9\cdot 0)/(-3)=0`

The value 0 has no sign. It exists between positive and negative numbers. It is neither positive nor negative.

We prepend a minus sign to negative numbers. The value 0 is usually written without such a sign, so might be considered to have a sign of +, just because it isn't –.
