Many students will know a lot of calculation rules when they study calculation. I've sorted out some product change rules. Let's have a look.

The law of product change is 1. When two numbers are multiplied, one factor is expanded (or reduced) by n times, and the other factor is unchanged, then their product is also expanded by n times. (n is a non-zero natural number).

2. If a factor is amplified by a factor and a factor is amplified by b times, the product is amplified by a*b times.

When two numbers are multiplied, one factor is enlarged by n times and the other factor is reduced by n times, so their products remain unchanged.

4. In the multiplication formula, one factor A is multiplied by m, another factor B is divided by n, and the product C is multiplied by m and then divided by n, (m≠0, n≠0).

5. In the multiplication formula, one factor A is divided by m, another factor B is divided by n, and the product C is divided by m and then divided by n, (m≠0, n≠0).

Variation law of product motion 1. One factor is multiplied by 10, and the other factor is unchanged. The product should be ().

2. When two factors are divided by 10 at the same time, the product should be ().

3. One factor is multiplied by 10, and the other factor is divided by 10, and the product is ().

4. The product of two factors is 96, where one factor remains unchanged and the other factor is divided by 3, and the product is ().

5. The product of two factors is 96, in which one factor is unchanged and the other factor is multiplied by 3, and the product is ().

The above is some information about the law of product change, I hope it will help you.
