Mathematics trick for some multiplication

Today I'm going to share all of you a new trick for calculating of mutiplication of10 base 100 base and 1000 base so on 10000........base

for 10 base
let us consider a number as 1X, 1Y We have to multiply this two number.
Stp 1: write down the last digit of the no. separately in right side. and also all no. rewrite in left side
LIKE
1X/+X or -X
1Y/+Y or -Y

---

Stp 2: multiply the digit of the right side directly.
LIKE
1X/+X or -X
1Y/+Y or -Y

---

         /XY 

St3: Add down the digits daigonaly
Like
1X/+X or -X
1Y/+Y or -Y

---

   1X  +Y   / XY  

For example
18 *15
18/8
15/5

---

23 /40
finally 23+4/0= 270

Now this 100 base trick
the rules is same as that of 10 base which is given above
let's try for 107*108
107/07
1O8/08

---

107+8  /56

i.e. 115/56
final ans 11556
so same way for 1000 base 10000........

N.B. : For 10 Base no right side should be taken only 1 digit, also for 100 Base no right side should be taken two digits. and similarly for 1000 Base no right side should be taken three digits.![WIN_20180225_18_04_03_Pro.jpg](https://cdn.steemitimages.com/DQmUTTNo3aHTAaMYREaZSrT3m6N73CWzp5RmqmbYJYYDpdt/WIN_20180225_18_04_03_Pro.jpg)
