Question

How do multiplication properties and division rules help you multiply and divide?

Answer 1

The properties of multiplication and division are an easier way when making calculations.

Let's see an example for each one.

Mutiplication:

Suppose we are going to multiply:

$2 * 89$

It is easier to make the product using the distributive property:

$2 * 89 = 2 * (80 + 9)\\2 * 89 = (2 * 80) + (2 * 9)\\2 * 89 = 160 + 18\\2 * 89 = 178$

Division:

Suppose we have the following division:

$\frac{2}{0}$

By properties of the division, we know that this division is not defined.

Therefore, when we see a division between 0, we know that the answer is that it is not defined.

Answer:

The rules of multiplication and division help to divide and multiply in a faster way.

Answer 2

Multiplication and division properties and rules help us multiply and divide simply because they guide these basic math operations in determining the proper outcome such as the product and quotient of the objective numbers. For example, take for instance the zero property of multiplication, it states that any digit that is multiplied by zero is zero. This simple property provides us an idea that when there is a scenario that we are given an equation that is 1 x 0, we can answer the equation immediately which is 0.
