How come that this works?

it doesn't

For one, my shoe size is two digits
Secondly, you just multiply the shoe size by a number with 100 as a factor, so when you add 2012, the last two digits are 12. When you subtract your birth date from that, you get obviously get your age.

You should change this to 2016 btw cause this would only work 4 years ago.

>12
>60
>110
>2200
>3212
>1228

this predicts that my shoe size is 1 and my age is 28.

my actual shoe size is 12 and im 31.

proved you wrong

>>7938352
1. X
2. 5*X
3. 50+5*X
4.1000+100*X
5.2012+100*X
6.(2012-Y) + 100*X

If the year was 2012, then of course 2012 minus your birthdate gives you your age.

They just multiply X by a hundred to get it to the front and out of the way of the other calculations.

It's funny that this math trick only works on children's shoe sizes because that's the only group it could fool.

Okay so my first go using my real size 9.5, it told me my shoe size is 9 which it is but my age was 67 then my second go using my rounded down shoe size 9 it told me I'm 17. I am neither 17 nor 67.

also, if your shoe size is a half measure, that absolutely fucks everything.

it also doesn't account for if your birthday has occurred this year or not

Hey guys, I tried to fix it

>>7938498
Now it only works in 2016
Also
>define "front"

1. TAKE THE YEAR YOU WERE BORN
2. NOW SUBSTRACT THIS FROM 2016
3. THE ANSWER IS YOUR AGE

HOLY CRAPERONI!
IT WORKS!

What if my birthday isn't till December?

Instructions that work for any year:

I. Take ur shoe size.
II. Multiply it by 100.
III. Add your age.

The 1st n digits is your shoe size, where n is the number of digits in your shoe size, while the last m digits is your age, where m is the number of digits in your age.

Prove me wrong if you can!

44
*5=220
+50=270
*20=5400
+2012=7412
-1995=5417

>good to know that my feet are actually almost nonexistant
>also good to know that Ill have to remember my 418th birthday in a few months

Thanks op.

First n digits, n being floor(log(shoesize))+1+Ceiling(fracpart(shoesize)) ;^)

> buh my shoe size is 11.25
No

>>7938741
last 2 digit is your age, you cuckfuck
says 17 but you're 21?

>>7938352
1: x = your shoe size
2: 5x
3: 5x + 50
4: 20(5x + 20)
5: 20(5x + 20) + 2012 = 100x + 1000 + 1012 = 100x + 2012
[current year] - [your birth year] w give you your age, wich we assume is a 2 digit number "a*10 + b", where 0=<a,b<=9 so we get:
100x + 10a + b
so it works if you replace 1012 with [current year] - 1000

Didn't work for me

>Shoe size: 11
>Age 28:

>11 x 5 = 55
>55 + 50 = 105
>105 x 20 = 2100
>2100 + 1012 = 3112
>3112 - 1988 = 1124

Add 1016 for this year then it works.
