"BREAKING THE CODE OF MATHEMATICS"

Hi, Guys!
Imagine a day when you are asked the square of 491 i.e.491^2. And you say the answer just in a few seconds without doing the calculations in a pen or a paper.

The people around you would be simply amazed.

And you know? This is simply VERY SIMPLE if you break the code of maths. You will also find that your brain is more efficient than your thoughts.

This code breaking will really help all the people of any range of age.

So now fasten your seat belts to undertake a simply amazing ride of the wonderful world of maths.

 I assure you it wont be a thrillarium ride for those who fear maths.

Multiplication

OK here comes the most interesting part.

Now if we consider a two 4 digit number, the multiplication would be taking place such that every number in the each 4 digit number is taken into consideration.

1-digit:

If we have the numbers 7 and 5:

                  7
                  5

only two numbers are there, so only 7 and 5 only would be involving in multiplication.

2-Digit:

           42
           76
now see the pattern:

This is new for you(maybe)

1. First 4 and 7
2. then 4*6+2*7
3.then 2 and 6

You can notice that somehow directly or indirectly each number comes into association.

If you put a diagram of sets of how the multiplication takes place, it would be:

The numbers rounded in red represents the first set multiplied.
The numbers in green borders represents the second set.
Similarly the blue the third set.

But why the second set involve multiplication?

Here is the number. You can also notice that a number say 7 of 26, comes two times in the multiplication operation. This is for a 2-digit number. It it was a three digit number, 7 would have come three times exactly in the multiplication operations. We can also say that 7 would have occurred in three sets.

Since numbers have been uniform since their invention by Nature, formulas like (a+b)^2 = a^2+2ab+b^2 exist.

Now you can be able to break the code of multiplication.

Now take a number (66)^2[read as 66 square].

If we take the above formula, in that take a=6. then bis also=6. Since a=6=b.But you may think why we should not take a=60. "Just believe me". Don't take care any zeroes for value calculation. I only mentioned not for value calculation. But zeroes are taken into consideration for digit calculation.

First we shall calculate what is 66 square.

1. What is 6 square i.e.a^2? It is 36.
2.You must have understood. Now calculate 2ab. It is 72.
3. Then b^2 is also 36.
4. If you had learnt the tacking up lesson in the addition lessons(If you had not learnt, please learn), Add the tenth digit to the previous number and simply attach the ones digit. then you get the answer 4356.

Try these calculations in your mind itself. You will be amazed to find that you are able to find that you will be able to square a two digit number in your mind.

Now try squaring the number 34.

Here "a" and "b" would be different. "a" would be "3" and "b" would be "4".

Now try to do in mind itself, although I will guide you. If you had practiced, Just check the number. If you find something had gone wrong, check out the steps for correction.

1. 3^2=9
2.2ab=24
3.b^2=16
4. Then tack up to find the answer. You should get 1156.

This is not only to find two digit numbers, but also to find the squares of any number of digits with two numbers having zeroes between them. For example take the number 34 itself, but insert two zeroes between 3 and 4. that would be 3004. The square of 3004 would be 9024016. Now Think how this answer came.

If you had estimated that, "since two zeroes are present in 3004 then one minus two is one, thus one zero is present between 9 and 24 and 16."THIS is wrong. It means you think too complex. Don't think too complex but think correctly. Actually the same number of zeroes as that in 3004 is present in the answer. But since we are tacking up the tenth digit is added to a zero before. Thus there are actually two zeroes. To prove, lets take 3001^2. The square would be 9006001.
