Some Tips and Tricks
It is best to put the whole table into your memory using Math Trainer - Multiplication, but here are some tricks that may help you remember your times tables.Everyone thinks differently, so just ignore any tricks that don't make sense to you.
The Best Trick
| Every multiplication has a twin, which may be easier to remember. For example if you forget 8×5, you might remember 5×8. This way, you only have to remember half the table. |
Tricks by Number
| to multiply by | Trick |
|---|---|
| 2 | add the number to itself (example 2×9 = 9+9) |
| 5 | The last digit always goes 5,0,5,0,.., |
| is always half of 10× (Example: 5x6 = half of 10x6 = half of 60 = 30) | |
| is half the number times 10 (Example: 5x6 = 10x3 = 30) | |
| 6 | if you multiply 6 by an even number, they both end in the same digit. Example: 6×2=12, 6×4=24, 6×6=36, etc |
| 9 | is 10× the number minus the number. Example: 9×6 = 10×6 - 6 = 60-6 = 54 |
| The last digit always goes 9,8,7,6, .. | |
| if you add the answer's digits together, you get 9. Example: 9×5=45 and 4+5=9. (But not with 9×11=99) | |
| 10 | put a zero after it |
| 11 | up to 9x11: just repeat the digit (Example: 4x11 = 44) |
| for 10x11 to 18x11: write the sum of the digits between the digits (Example: 15x11 = 1(1+5)5 = 165) Note: this works for any two-digit number, but if the sum of the digits is more than 9, you will have to "carry the one" (Example: 75x11 = 7(7+5)5 = 7(12)5 = 825). | |
| 12 | is 10× plus 2× |
Remembering Squares Can Help
This may not work for you, but it worked for me. I like remembering the squares (where you multiply a number by itself):| 1×1=1 | 2×2=4 | 3×3=9 | 4×4=16 | 5×5=25 | 6×6=36 |
| 7×7=49 | 8×8=64 | 9×9=81 | 10×10=100 | 11×11=121 | 12×12=144 |
| 5×5 = 25 is just one bigger than 6×4 = 24 |
| 6×6 = 36 is just one bigger than 7×5 = 35 |
| 7×7 = 49 is just one bigger than 8×6 = 48 |
| 8×8 = 64 is just one bigger than 9×7 = 63 |
| etc ... |
