EASY MATHEMATICS CALCULATION

Mathematics is an easy subject. India is a country which is known for its mathematicians. All great mathematicians starting from the great Aryabhatta to great Ramanujan were born in India. But it is a very shameful fact that the present generation of students find it “wasteful” and “fearsome” topic. In my first blog I am going to introduce some easy tricks which could be beneficial for those who have fear in it.

At first I will show you an easy process of multiplying and number with the repetition of the digit “9′.So lets start this by taking an example:-

Multiplication of 64585 with 99999:-

64585*99999=6458435415

The steps of solving this critical multiplication are as follows;-

i) We subtract 1 from 64585 and write half of the answer as 64584. Answer at this stage is 64584_

ii)Now we will be dealing with 64584. Subtract each of the digits 6,4,5,8 and 4 from 9 and write the one by one.

9-6=3;9-4=5;9-5=4;9-8=1;9-4=5

iii)The answer already obtained was 64584 and now we suffix to it the digits 3,5,4,1 and 5. The complete answer is 6458435415.

We can take various examples like 3656,5644,9821,3645,2548,etc for doing this technique.
