Maths Magic



Funs with Figure: Is it Math or Magic?

A lot of us seem to struggle so badly in math. Its like no matter what we do to understand every equation we never get how it's done and we always got the wrong calculations. Math can be very difficult to master.
over 3000 years ago in Ancient India, the Vedics devised a system of mental math based around the way the mind naturally works. Their ways and patterns are quite different to the methods we have today. It is most simple and effective. During 20th century it was rediscovered however it did not became famous and readily accessible to the public.

Examples of these are ways to multiply any 2-digit numbers together in your head within seconds! Like 26 x 38… does that look hard? It's simple when you know this ingenious method of multiplication. How to calculate naturally - from left to right, he easiest method ever for dealing with fractions and a lot, lot more!
Don't worry this is not another copy of your calculus, algebra or statistic book rather a 52 easy-to-follow pages that are presented in plain, simple language that shows you exactly what you need to do, examples and quizzes where you can practise yourself with your new math skills.
For example lets see some magic of maths that can be used by you to make your friends jealous of you and they will proud on you.
Believe it or not, numbers can be fun.  Here are a few examples -
*     Sum of Human Knowledge (contributed by Eric Bishop)
If you multiply the number 142,857 by anything between 1 and 6 the answer contains the same digits. 
e.g. 142857 x 3 = 428571      and       142857 x 6 = 857142
If you multiply the same figure by 7 the answer is 999,999.

See its a kind of fun or u can say a magic to your friends. There are many these type of magic or which can be done by us ...... let see


*     A game to find out a person's age and how many coins they are carrying.
·         Ask someone to double their age (either mentally or on paper) but, obviously, they must not tell you.
·         Then to add 5 and multiply by 50.
·         Finally, they must add the number of coins they have on them.   If they do not have any, nothing is added.
·         They then tell you the final answer.
·         Now all you have to do is take away 250.  The first two digits of the answer you are left with are the persons age and the last two the number of coins in their possession.
This works unless they are carrying over 100 loose coins.
Example -   25 x 2 = 50 + 5 = 55 x 50 = 2750 + 6 = 2756
                     2756 - 250 = 2506


This is surely u can say a magic if you try this with your friends, they will surely ask you that how did you do that.
