What is the combination property of multiplication?

The combination property of multiplication is the combination law of multiplication.

The combination law of multiplication is written in the form a * (b * c) = (a * b) * c.

In order to multiply a certain number by the product of two other numbers, you can first multiply the first number by the second number, and then multiply by the third number, and vice versa, multiply the first number by the third number, and then multiply by the second number.

The combination property of multiplication is used to facilitate the solution of examples. Using the combination law of multiplication, you can choose the simplest way to solve the example.

Solving examples using the combination property of multiplication
20 * (5 * 9) = (20 * 5) * 9 – the combined property of multiplication.

To facilitate the solution of the example, the first number 20 is multiplied by the second number 5, since multiplication shows that 20 multiplied by 5 gives 100, that is, 20 * 5 = 100. Then we multiply by the third number 9, that is, we get: 100 * 9 = 900.

As a result, we get 20 * (5 * 9) = (20 * 5) * 9 = 900.

Let’s solve similar examples using the combination property:

4 * (25 * 3) = (4 * 25) * 3 = 100 * 3 = 300;
2 * (100 * 15) = (2 * 100) 15 = 200 * 15 = 3000;
(60 * 35) * 2 = 60 * (35 2) = 60 * 70 = 4 200.
