# Multiplication Of Integers

Multiplication of two integers is the repeated addition.

Example

Now letâ€™s see how to do the multiplication of integers without the number line.

### 1. Multiplication of a Positive Integer and a Negative Integer

To multiply a positive integer with a negative integer, we can multiply them as a whole number and then put the negative sign before their product.

So the product of a negative and a positive integer will always be a negative integer.

### 2. Multiplication of Two Negative Integers

To multiply two negative integers, we can multiply them as a whole number and then put the positive sign before their product.

Hence, if we multiply two negative integers then the result will always be a positive integer.

### 3. The Product of Three or More Negative Integers

It depends upon the number of negative integers.

a. If we multiply two negative integers then their product will be positive integer

b. If we multiply three negative integers then their product will be negative integer

If we multiply four negative integers then their product will be positive integer
