# Why does a negative time a negative equal a positive?

**Solution:**

We know that negative times anything means that it will change the sign.

Now, let's have a negative number. We multiply it with another negative number. For example, -3 × - 9 = 27

Ideally, the second negative should change the sign of our original number (which is also negative).

So, our original negative sign is changed into a positive sign when a negative is multiplied to it.

Thus, As multiplying with negative will change the sign, a negative times a negative equal a positive.

## Why does a negative time a negative equal a positive?

**Summary:**

As multiplying with negative will change the sign, a negative times a negative equal a positive
