**How to easily calculate multiples of 9?**

To calculate an exercise involving multiplication by 9, we will look at the number that appears in the exercise. We subtract 1 from it, and the number we get is the tens digit in the product.

To calculate the one’s digit, we will subtract from 9 the number we got in the tens digit calculation. The number we get is the unity digit in the product.

For example, consider the 9×7 exercise.

In the exercise, the number 7 appears. We will subtract one from it and get:

7-1=6

Therefore, the number 6 is the tens digit in the product.

Now, consider the unity digit. We will subtract 6 from 9 and get:

9-6=3

Therefore, the number 3 is the unity digit in the product.

In conclusion,

7×9=63

**Interesting to know**

Multiples of 9 are numbers whose sum of digits is 9. For example, the sum of the digits of the number 81 is 8+1=9, therefore 81 is a multiple of 9.
