.

Subsequently, one may also ask, how do you multiply and divide negative numbers?

The multiply/divide sign rule:

  1. If the 2 numbers you are multiplying or dividing. have the SAME sign (+,+ or -,-) then the result is POSITIVE.
  2. If the 2 numbers you are multiplying or dividing. have DIFFERENT signs (+,- or -,+) then the result is NEGATIVE.

Also Know, how do you divide negative numbers? The rule for multiplying and dividing is very similar to the rule for adding and subtracting.

  1. When the signs are different the answer is negative.
  2. When the signs are the same the answer is positive.

In respect to this, what is a negative number multiplied by a negative number?

Rule 3: A negative number times a negative number gives you a positive number. Example 3: This is also new—and doesn't seem to make much sense, but it is a rule we have to follow when multiplying negative numbers together. So, for example, we may have the problem -3 x -4.

What are the rules for adding positive and negative numbers?
