Fantastic Math Tricks


Multiply Up to 20X20 in Your Head

In just FIVE minutes you should learn to quickly multiply up to 20x20 in your head.


 

With this trick, you will be able to multiply any two numbers from 11 to 19 in your head quickly, without the use of a calculator.

I will assume that you know your multiplication table reasonably well up to 10x10.    

Try this:

That is It! wasn't that easy? Practice it on paper first!

The Multiple of 11 Rule

You likely all know the Multiple of 10 rule (to multiply by 10, just add a 0 behind the number) but do you know the 11 rule? It is as easy! You should be able to do this one in you head for any two digit number. Practice it on paper first!

To multiply any two digit number by 11:

The only thing tricky to remember is that if the result of the addition is greater than 9, you only put the "ones" digit in the hole and carry the "tens" digit from the addition. For example 11 x 57 ... 5__7 ... 5+7=12 ... put the 2 in the hole and add the 1 from the 12 to the 5 in to get 6 for a result of 627 ... 11 x 57 = 627


Practice Finger Math: 9X Rule


To multiply by 9, try this:
(1) Spread your two hands out and place them on a desk or table in front of you.
(2) To multiply by 3, fold down the 3rd finger from the left. To multiply by 4, it would be the 4th finger and so on.
(3) The answer is 27 ... READ it from the two fingers on the left of the folded down finger and the 7 fingers on the right of it.

Square a 2 Digit Number Ending in 5


For this example we will use 25


Try a few more 75 squared ... = 7x8=56 ... put 25 behind it is 5625.
55 squared = 5x6=30 ... put 25 behind it ... is 3025.

Square any 2 Digit Number with UP-DOWN Method

This works for anything up square 2 Digit Number

Square a 2 Digit Number, for this example 37:


With practice this can easily be done in your head.

+ ur AGE
+ 365
and
- 615.
The last
2 no. is
ur age
1st no. is
ur cells last no
JUST TRY IT!

Cell Number

ur cell’s number last digit X 2+5X50+ur age+365-615
the last 2 number is ur age first number is ur cell’s last number
just try it…
2- Your Age in triple figure
259 X (YOUR AGE) X 39= ANSWER (?)
Try it and u will be surprised 2 see Da result

3- Calculation
can you think how “1+4+3=10″ came?
think think !!
dont know?
plz use your brain?
didnt get?
ok i tell you how it came
simple by
“MISTAKE”
4-Age Calculation Tricks:
Step1: Multiply the first number of the age by 5. (If <10, ex 5, consider it as 05. If it is >100, ex: 102, then take 10 as the first digit, 2 as the second one.)
Step2: Add 3 to the result.
Step3: Double the answer.
Step4: Add the second digit of the number with the result.
Step5: Subtract 6 from it.
