No. Multiplying or dividing by a negative number is perfectly valid. However, please note that:

- Dividing by zero will most likely give you wrong results.
- In the case of an inequality, if you multiply or divide by a negative number, you have to reverse the sign. For example, 2 < 3; multiplying by -2: -4 > -6

You will end up with a positive number. With integers, if you multiply or divide an even amount of negative numbers, the answer will be positive and if you multiply or divide an odd amount, the answer will be negative.

You multiply the negative number by the reciprocal of the fraction.

Adding negatives? You get a negative. But if you multiply/divide 2 negatives, that's a positive.

If you multiply or divide the numbers, the answer will be negative.

You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.Positive x positive = positiveNegative x negative = positiveWhen you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.Positive x negative = negativeNegative x positive = negative.
