## Rules for Multiplying Negatives

We may have positive and negative numbers when doing with entities in multiplication. There are some common rules for multiplying numbers.

Example |
|||

two positive signs make a positive sign: | 4 × 5 = 20 | ||

two negatives signs make a positive signs: | (−4) × (−5) = 20 | ||

a negative signs and positive signs make a negative sign: |
(−4) × 5 = −20 | ||

positive signs and negative signs make a negative sign: |
4 × (−5) = −20 |

** Note**

- As we know that “
**+**” is the positive sign - And “
**−**” is the negative sign. - When a number has
**no sign**, it normally indicates it’s**positive**.

**For example,** **6** is really **+6**

We can use pair of brackets **()** around the numbers to avoid confusion.

**For example,** **6 × −5** can be written as **6 × (−5)**
