# INTEGER MULTIPLICATION AND DIVISION RULES

## About "Integer multiplication and division rules"

Integer multiplication and division rules :

Here we are going to see rules in multiplication and division.

• Whenever we want to multiply or divide two integers with same sings, we have to put positive sign for the answer.
• Whenever we want to multiply or divide two integers with same sings, we have to put negative sign for the answer.

Note :

If negative sign appears odd number of times, then the answer will have negative sign.

If negative sign appears even number of times, then the answer will have positive sign.

## Integer multiplication and division rules - Examples

Let us see some examples problems based on the above concept.

Example 1 :

Is (-10) × (-7) positive or negative?

Solution :

Multiplying two negative signs will become positive.  So the final answer is positive.

Example 2 :

Is 7 × (-7) positive or negative?

Solution :

Here negative sign appears odd number of times, so the answer will have negative sign.

Example 3 :

Is 14 × (-12) x (-11)  positive or negative?

Solution :

Here negative sign appears even number of times, so the answer will have positive sign.

Example 4 :

Is (-2) × 3 x (-7)  positive or negative?

Solution :

Here negative sign appears even number of times, so the answer will have positive sign.

Example 5 :

Is 1 × (-5) x (-4) x (-2) positive or negative?

Solution :

Here negative sign appears odd number of times, so the answer will have negative sign.

Example 6 :

Is (-5) x (-4) positive or negative?

Solution :

Here negative sign appears even number of times, so the answer will have positive sign.

Example 7 :

Is (-3) x (-15) x (-2) positive or negative?

Solution :

Here negative sign appears odd number of times, so the answer will have negative sign.

Example 8 :

Is 2 x (-5) x (-1) positive or negative?

Solution :

Here negative sign appears even number of times, so the answer will have positive sign.

Example 9 :

Is (-3) x (-2) x 5 positive or negative?

Solution :

Here negative sign appears even number of times, so the answer will have positive sign.

Example 10 :

Is 4 x (-3) x (-2) positive or negative?

Solution :

Here negative sign appears even number of times, so the answer will have positive sign.
