The Beauty Of 9th
When I Was A Kid, I have been teached by my teacher to learn some mathematic formula to speed up my calculation. I think everybody knew about this:
Any single Digit Times By 9 will be : [x-1] & [9 - (x-1)]
• x= Single Digit
Which mean
if 7 X 9 : it will be
=[7-1] & [9-(7-1)]
=6 & 3
=63
Or
if 9 X 9 : it will be
=[9-1] & [9-(9-1)]
=8 & 1
=81
But I have found something that it is not limited only for a single digit. Let me show you how I can calculate a huge number if the pair is 9
For example:
1) 237 X 999
2) 123456 X 999999
3) 32553532653 X 99999999999
Let say :
X =237
Y =999
Some expert person calculate it like this
X * Y = [X (Y+1)] – X
=[237(1000)]-237
=237000 – 237
=236,763 #
And This Is My Formula
X * Y = [X-1] & [Y-( X-1)]
=236 & 763
=236,763#
If you make some prediction, each of the number has a pair that equal to 9
2 with 7 = 9
3 with 6 = 9
6 with 3 = 9
So it easy for you to solve the problem number 2 and 3.
- Ignore the entire 9 group
- Put all other digits with minus 1 and make the pair
2) 123456 X 999999 = 123455 & 876544
=123,455,876,544 #
3) 32553532653 X 99999999999 = 32553532652 & 67446467347
= 3,255,353,265,267,446,467,347#
So now do you think you can beat Super Intelligent Computer Huh!
If Microsoft or any Super Computer Designer knew about this formula, maby it will be no longer 8 bits ,16 bits ,32 bits , 64bits,128 bits or bla.. bla ..bla…
It is just Only 9++ bits in the future.
Good Luck
If you feel lucky for this code, why not just buy me some coffee ![]()
