fast calculation in maths



calculation of simple arithmatic than usual method.

like for example:

if u want to multiply 99971 by 99988 without using pen/paper


99971
*99988
-------- 100 - 71=29
100 - 88=12

then 29* 12= 348 ,so put 348 at end then since the numbers are five digit make it five digit like 00348.then multiply lesser number (12) unit placenumber (2) ( 2*29=58)

then add (58+1)

put as 5400348

then the three numbers which are similar 999 before what we got from the above process like 9995900348.

now u get the value without pen and paper aith just ur brain faster than usual conventional method
.

there are several methods just u can try urself
