Top Math Tricks for Creative Mind Blowing kids
Not everyone is a master at juggling numbers, but the subject isn't as complicated as it seems if you make use of simple maths tricks that will make solving any math problem a piece of cake!
To understand maths easily, the subject can be seen as a game of building blocks stacked on one another — the base must have a strong foundation to move into more complex concepts and tough applications.
Same Three-Digit Number
Think of any three-digit number in which each of the digits is the same. Examples include 333, 666, 777, and 999.
Add up the digits.
Divide the three-digit number by the answer in Step 2.
The answer is 37.

Six Digits Become Three
Take any three-digit number and write it twice to make a six-digit number. Examples include 371371 or 552552.
Divide the number by 7.
Divide it by 11.
Divide it by 13.
The order in which you do the division is unimportant!
The answer is the three-digit number.
| Example |
371371 gives you 371 or 552552 gives you 552.
A related trick is to take any three-digit number.
Multiply it by 7, 11, and 13.
The result will be a six-digit number that repeats the three-digit number.

The 11 Rule
The 11 rule is one of those magic tricks and methods that can be used to quickly multiply two-digit numbers by 11 in your head.
Separate the two digits in your mind.
Add the two digits together.
Place the number from Step 2 between the two digits. If the number from Step 2 is greater than 9, put the one's digit in the space and carry the ten's digit.
| Example |
72 x 11 = 792.
57 x 11 = 5 _ 7, but 5 + 7 = 12, so put 2 in the space and add the 1 to the 5 to get 627
