Tricks of the 9 times table

The 9 times table can be really easy to learn if you know some simple tricks!

Notice what happens to the tens and ones column:

1 脳 9 = 097 脳 9 = 63
2 脳 9 = 188 脳 9 = 72
3 脳 9 = 279 脳 9 = 81
4 脳 9 = 3610 脳 9 = 90
5 脳 9 = 4511 脳 9 = 99
6 脳 9 = 5412 脳 9 = 108

Can you see how the ones column is decreasing by one each time until it reaches zero and it goes back to 9?

The tens column increases by one each time.

Example 3

Boy asking a question

Use 108 梅 12 = 9 to solve 10,800 梅 __ = 12

The first thing to do is compare the two divisions.

The missing number will be a multiple of 9 since that fact is missing.

Now, compare the dividends (the number being divided).

10,800 is 100 times larger than 108.

The 12 has stayed the same value, so that means the missing number must also be one hundred times larger!

9 x 100 = 900

Therefore:

10,800 梅 900 = 12

This is where your knowledge of multiplying by 10 and 100 also comes in handy!
