If you multiply two positive numbers, or two negative numbers, the result will be positive.

If you multiply a positive and a negative number, the result will be negative.

The same rules apply for division - a positive number divided by a negative number, or a negative number divided by a positive number, will give a negative result.

In any case, most of the calculation is the same as for positive numbers - you only have the additional complication of deciding whether to put a plus sign or a minus sign in front of the result. For example, -8 / 2 = -4; the absolute value (4) is the same as when you divide 8 / 2, only the sign changes.

If you multiply two positive numbers, or two negative numbers, the result will be positive.

If you multiply a positive and a negative number, the result will be negative.

Multiplying and dividing integers is real easy. All you have to do is do regular dividing and multiplying keeping in mind these simple rules: RULES: 1: When multiplying or dividing integers, when the numbers are a positive, positive they equal a positive. When the numbers are negative, negative they equal a positive. In other words, same signs equal positive. 2: This rule is very similar to the rule above. The only change is that when the signs are different, they equal a negative. ( negative, positive= negative, positive, negative= negative.) Please correct me if I'm wrong.
