Question

What is the sign of the product of a three negative numbers?

Answer 1

Answer:

Sign of the product of 3 negative numbers is -

For example,

(- 2) × (- 2) × (- 2) = - 8

Because, one minus cuts from another one then, only one minus lefts.

We can not cut that remaining minus with its similar sign, because there is no similar sign anymore.

So, I just want to say that,

+ × + = +

- × - = +

- × + = -

+ × - = -

Thank you!
