This trick just BLEW my mind!

This **** is stupid. Even if my example is incorrect and I got it wrong, it's still stupid because in most cases you'll end up having to divide and multiply large numbers anyways. Such as 15 x 68.
Just do as you were thought in school, it's much easier
Assuming you all were thought the same method as I was

i'm just gonna use a god damn calculator.

yall *********** be over complicating everything.

Just so you know it works for numbers not as close to 100 too, though it tends to be a little more difficult. 82 x 73 = 5986...100-82 = 18, 100 - 73 = 27, 18 x 27= 486, 18+27=45. Now here's the silly part, if the number of the mulitplication is triple digits you have to subtract the first number, in this case 4, from the addition, which is 45 so 45-4=41. 100-41=59, not add on the last two digits of your multiplication and you get 5785. 65 x 89 = 5785. 100-65= 35, 100-89=11, 35 x 11=385, 35+11=46, 46-3=43, 100-43=57, add on the 85 from the multiplication and you get 5785. Did it twice just to prove (mostly to myself) that it wasn't a fluke.

86 x 93...ok I got this.  14 + 7 = 21 - 100 = 79.  So far so good, now to just multiply 14 by 7...						****					.

Tried it with 50x50 (simplest one that came to my head)   
Got some recursive 						****					, wrinkled my brain man.

okay...

Cracked the math.



I have no idea why I did it though, I have much better things to do...

Until the day comes that we all carry calculators everywhere we go, we need to know **** like this.

ya cause this will make 76X43 sooo much easier
#78 - psykobear (04/27/2014) [+] (8 replies)
Except that there is a much easier method that actually works all of the time, for numbers of any size.
I present: The Lattice Method
9x9=81, 7x9=63, 9x6=54, 7x6=42
2=2, 4+4+3=11(or 1, carry 1), 1+1+6+5=13(or 3, carry 1), 1+8=9

I don't even know what the **** i'm looking at and really don't feel like figuring it out.

This trick only work for 9X * 9X though.
Like, it doesn't work if it's 4X * 8X

Use this methode to do this:
45 X 55

it's wrong.

according to this **** 86 x 90 should be 24140 but it is 7740
