Tricks in 25

Math always has its explanation to understand. In this session, we going to discuss some of the tricks and logic behind the formula or the math function.
( We already discussed for the number 5,
Tricks in number 5)
Tricks in number 25.
How you will multiply any number with 25?
We all know the traditional method,
2 * 25 = 50
4 * 25 = 100
6 * 25 = 150,.....likewise its goes on.
What you do if the number of digits increases with this function, yes the traditional method gives an answer but it takes time and the same bored method.
Here comes the math explanation. We just listen to it for a while, we all know how easy to multiply with the number 100. It says just add two zeros, at last, no matter how long the digits are it works in the same way.
And we also know that 100is also represented as 25 * 4.

Here comes the trick revels
24 * 25 = (2/4)(24/4)(no remainder so add two zero) = 0600
482 * 25 = (4/4)(8/4)(2/4, it will not divide so we add one zero )(no remainder so add one zero) = 12050

2468* 25 = (2/4)(4/4)(6/4)(8/4)(no remainder so add two zero) = 061700
26848642 * 25 = (2/4)(6/4)(8/4)(4/4)(8/4)(6/4)(4/4)(2/4 it will not divide so we add one zero )(no remainder so add one zero) = 067121650

As simple as that math is always easy.
