## Math Magic Tricks to wow your children

1. ### The answer is always 5

This trick always works!

Start by thinking of a number.

Double it.

Halve it.

Try this with different numbers and wow your audience with this simple math magic trick.

1. ### I know how much money you got!

Without giving you any information, ask the students to count the value of a random set of coins and write the amount on a piece of paper. Then ask them to follow the next steps-

Double the amount.
Add the first odd prime number to the new total.
Multiply the result by 1/4 of 20.
Subtract the lowest common multiple of 2 and 3.

For the final answer –  Take off the last digit and you will be able to guess how much the coins are worth!

1. ### Guess their age and shoe size!

Ask your child to follow the given directions but not present any of the calculations to you –

Ask them to write down their age
Multiply it by 1/5 of 100.
Add on today’s date (e.g. 2 if it’s the 2nd of the month).
Multiply by 20% of 25.
Now add on your shoe size (if it’s a half size round to a whole number).
Finally, subtract 5 times today’s date.

The hundreds are the age and the remaining digits are the shoe size. If for instance, somebody shows you 1206, there are 12 hundred – the age, and the remaining digits 06 (or 6) denote their shoe size. 1. ### The correct answer is always 37!

To perform this trick, ask any of your friends to choose a three-digit number with the same digits.

For example, 222
Add the digits together. So, 2+ 2 + 2 = 6
Divide the original number with this sum. So, 222 / 6 = 37.

Works every single time!

1. ### Learn how to add 2-digit numbers at the drop of a hat!

Get a firm understanding of the basic principles of tens & unit places, and you will be able to add two-digit numbers at a lightning-fast speed.

For example, take two, two-digit numbers,

Like, 57 + 79.

Then, split the 2nd number into tens & units, making it 79 = 70 + 9.
After that ,move up  up the tens addition, which is 57 + 70 = 137.
To get the final answer, you must add the left units place digit, which is 137 + 9 = 146.

Isn’t this easy?

1. ### Predict any number!

To start with this math magic trick, choose any number like 22

Subtract one from it,  22 – 1 = 21
Multiply it with three. (21 x 3 = 63)
Add 12 to this number. (63 + 12 = 75)
Divide it with three. (75 / 3 = 25)
Now add 5 to the above number. (25 + 5 – 30)
Finally, ask your peers to subtract the original number from the above sum.
The answer will always be 8. (30 – 22 = 8) 1. ### Turn six digits into three

To do this trick, take any three-digit number and write it twice to make a six-digit number.

Like 371371
Then divide the number by 7 which is 371371/7 = 53,053
Then, Divide it by 11 which is 53,053 / 11 = 4823
Then, Divide it by 13 which is 4823/13 = 371
The answer is the three-digit number. Therefore, 371

1. ### Choose any number, your end product will only be 2!

To perform this trick ask your friend to think of a number, let’s say 8

Multiply it with three. (8 x 3 = 24)
Then, Add 6 to this number. (24 + 6 = 30)
Then, Divide it by three. (30 / 3 = 10)
Finally, Subtract the number chosen in step 1 with step 4 (10–8= 2)
The answer will always be 2!

1. ### The 11 Rule

By using this trick you can learn to quickly multiply any number with 11 mentally.

Choose any number and separate the two digits in your mind.

Place the number from Step 2 between the two digits.

If the number from Step 2 is greater than 9, but keep the one’s digit in the space and carry the ten’s digit.
Examples: 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. 1. ### Multiplication at your fingertips!

Did you know that you can effectively multiply any number of digits using your hands?

A simple way to do the “9” multiplication table is to place both hands in front of you with fingers and thumbs extended.

To multiply 9 by a number, fold down that number finger, counting from the left.

For example – to multiply 9 by 5, fold down the fifth finger from the left. Count fingers on either side of the “fold” to get the answer. In this case, the answer is 45.

## What is the 9 trick in math?

Start by thinking of a number, any number. Now, multiply that number by 9. If the result is a multi-digit number, add its digits together to come up with a new number. If that new number is still a multi-digit number, add its digits together to come up with yet another new number.

## How does the 1089 trick work?

The mystery is this: first, take any three digit number, where the first and last digits differ by two or more and reverse the number to produce a new one. Then subtract the smaller from the larger producing another new number. If you reverse this number and this time add the two, the result will always be 1089.
