Signs of results of multiplication and division

If two non-zero numbers have the same sign, and they are multiplied together, the end result will be positive.

For instance:

2 and 4 are positive; so, 8 is positive

-2 and -4 are negative; so, 8 is positive

If two non-zero numbers have different signs, and they are multiplied together, the end result will be negative.

For instance:

-2 is negative, and 4 is positive; so, -8 is negative

2 is positive, and -4 is negative; so, -8 is negative
