Why is that -2 X -3 = +6?

We'll recall the rules of multiplying 2
integers:

- multiplying 2 positive integers, you'll get a positive
integer, too:

(+2)x(+3) = +6

-
multiplying a positive integer and a negative integer, you'll get a negative
integer:

(-2)x(+3) = -6

(+2)x(-3) =
-6

- multiplying 2 negative integers, you'll get a positive
integer:

That is why (-2)x(-3) = +6
