Multiplication table A multiplication table makes it easier for you to perform operations. I strongly recommend that you learn it and know it by heart.

The multiplication table contain some interesting patterns that can help you remember some of those multiplications

First,notice that any number times 0 will give 0.

2 times 0 = 0

5 times 0 = 0

Any number times 1 will give the number

6 times 1 = 6

9 times 1 = 9

When you multiply any number( the number must be between 1 and 12; It may not be true for other higher numbers) by 9, the sum of the digits for the answer add up to 9.

For instance,

9 times 3 = 27 and 2+7 is 9

9 times 7 = 63 and 6 + 3= 9

See if you can find other interesting patterns that will help you remember the multiplication table!
