how do you multiply intergers

EX.....

-4 x 5 = -20

4 x 5 = 20 right?
Well the negative 4 makes your answer into a negative number also.

Do you get it now?

Yes, you are correct. To multiply integers, you need to understand the concept of positive and negative numbers.

When you multiply two integers with the same sign (both positive or both negative), the product will be positive. For example, when multiplying 4 and 5, both of which are positive, the answer is 20.

However, when you multiply an integer with a different sign (one positive and one negative), the product will be negative. In your example, when multiplying -4 and 5, since one number is negative, the answer is -20.

To summarize:
- Positive x Positive = Positive
- Negative x Negative = Positive
- Positive x Negative = Negative

In order to multiply integers, you simply multiply the absolute values of the numbers and then take into account the sign.
