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.

Maths Tricks in Number 5

We all know that Math has its formula for their numbers. Everyone afraid of the way Math representing nature, but it's so kind to all. It 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.

Tricks in number 5.

How you will multiply any number with 5?

We all know the traditional method, 

5 * 2 = 10

5 * 10 = 50

5 * 50 = 250,.....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 10. It says just add one zero, at last, no matter how long the digits are it works in the same way.

And we also know that 10 is also represented as 5 * 2. It says that the answer comes from multiply by 5 and the same answer divide by 2 is equal.

For instance, 

1. 250 * 10 = 2500
2. 2500/2 = 1250
3. 250 * 5 = 1250

From 1 it says the traditional method. From 2 and 3 the answers are equal but the functions are different.

Here comes the trick revels

24 * 5 = (2/2)(4/2)(no remainder so add one zero) = 120

482 * 5 = (4/2)(8/2)(2/2)(no remainder so add one zero) = 2410

2468* 5 = (2/2)(4/2)(6/2)(8/2)(no remainder so add one zero) = 12340

26848642 * 5 = (2/2)(6/2)(8/2)(4/2)(8/2)(6/2)(4/2)(2/2)(no remainder so add one zero) = 134243210

So easy right! Wait, what if the numbers or odd?

Simple just carry over the remaining to the next number.

234 * 5 = (2/2)(3/2)(14/2)(no remainder so add one zero) = 1170

784 * 5 = (7/2)(18/2)(4/2)(no remainder so add one zero) = 3920

2689 * 5 = (2/2)(6/2)(8/2)(9/2)(Add that remaining 1 to the 0, 10/2) = 13445

213 * 5 = (2/2)(One will not divided by 2 so we add that one to next number and put 0 for that place)(13/2) = 1065

As simple as that Math is always easy.
Practice this method then you dont worry about this function in number 5.
