To multiply any number by 4, simply multiply it by 2 and then double the answer.

35 x 4
35 x 2 = 70
70 x 2 = 140
35 x 4 = 140

Multiplying by 9

Hold up both hands, with your fingers spread. To multiply 4 x 9, bend your fourth finger from the left. Count the number of fingers to the left of your bent finger—you should get 3. Then count the number of fingers (and thumbs) to the right of your bent finger—you should get 6. The answer is 36. This works when multiplying any number 1-10 by 9.



multiplying by 11 Here’s how, using an example: 52 x 11.

The first digit of the answer will be 5 and the last digit of the answer will be 2. To get the digit between, just add 5 and 2.

5 (5+2) 2
572

You may have noticed that when you add the two digits together, you get a one-digit number. If you get a two-digit number, things are a little trickier.

87 x 11
8 (8+7) 7
8 (15) 7
(8+1) 57
957


Multiplying by 12 Let’s try it with 7 x 12.

First multiply 7 by 10. Then multiply 7 by 2. Finally, add them together.

7 x 12
7 x 10 = 70
7 x 2 = 14
70 + 14 = 84

final math trick, when there is a number that is being multiplied by two the trick is to just double the number!

You need basic math to do higher math, so nope.

If you want to see if a number is fully divisible by 3, add all the digits together and keep going till you get 1 digit, and see if it's a 3, 6 or 9.

Example: The number 282657

Adding all the digits together gives 30, and adding those 2 digits gives 3 (duh). So yes, it's divisible by 3, then you do mathemagic and get 94219.
