got it? ok

add a zero to the end (ex: 6 -> 60)
subtract your original number
add up the digits (ex: 43 -> 4 + 3 = 7)
double the result

find the corresponding letter of the alphabet if a=1, b=2, c=3, etc.. here's a handy chart
a  b  c  d  e  f  g  h  i  j  k  l  m  n  o  p  q  r  s  t  u  v  w  x  y  z
1  2  3  4  5  6  7  8  9  10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

now think of a color that begins with that letter

look at your keyboard and find that letter. look at the key to the left (if possible). think of animal that begins with that letter

ok now check out this song

Pi add 0 = pi minus pi = 0 double = 0

I chose 1.53 because I figured you were setting us up and you didn't specify that it had to be an integer.

chris: 1.53 still works with some modifications. you have to take 'add zero to the end' to mean multiply by ten. that way you'll get 15.3 - 1.53 = 13.77. when you add the digits you get 18, and if you add those digits you'll get 9.

that iterative process will result in 9 for every non-zero positive rational number. proof is left as an exercise to the reader. theo's choice of an irrational number is more troublesome. idk how to modify the process to make that work but i'll think about it.

alright I'll try an irrational number

a=e
a1=e x 10^1
a2=e x 10^1 - e

"add up the digits"

at 10 decimal places e is equal to 2.718281828

a3=9 x 2.718281828
=24.46453645

a4=[2+4+4+6+4+5+3+6+4+5]
=43

43 x 2 = 86

I'll assume the letter system repeats and adds a new letter similar to any numerical system.

therefore 86 = CH

then that makes XG

****ed if I know what starts with XG

Try writing as a series

let's say your number is A

((10A) - A) = 9A

you're essentially multiplying your original number by 9

now i need to find out how to prove that multiplying a number between 1-10 by 9 will always equal a number whose digits add up to 9.

**** how do you do that

assume a+b = 9 (0=<a,b=<9 or something) (a is the first digit of whatever you get by multiplying A by 9, b is the second digit e.g. 9x7 = 63, a = 6, b =3)
so b = 9 - a

well if we're essentially multiplying our original number A by 9, then... let's try this:

9A = 10a + b

if a is the first digit, you have to multiply it by 10 for the answer to be proper (e.g. 9*6 = 54, or 5*10 + 4)

b = 9 - a

so

9A = 10a + (9-a)
9A = 9a + 9
A = a + 1
therefore
a = A - 1

so the first digit (a) of any number (A) multiplied by 9, is A - 1. but that only works for A between 1-10, why did that happen?... oh, because i only chose a and b, two digits. it only works as long as the answer is two digits long.

so A - 1 = a, but a = 9 - b
A - 1 = 9 - b
b = 10 - A

the second digit (b) of any number (A) multiplied by 9, is 10 - A.

now, does a+b=9 when you plug in those things?

(A-1) + (10-A) = 9
9 = 9

so no matter what A you choose, the digits of the product will always add up to 9.

i think i cheated though, i'm not sure if i'm allowed to assume 9=a+b and then just draw my conclusion from that. it's circular or something.

help

edit: in all fairness i haven't done proofs in like 5 years

its only 1-10 so you can prove it for each one. No one said this had to be a general proof

Quote by Pastafarian96
also what about imaginary numbers? What about (-3)^1/2 ?

Thats not between 1-10

GENERAL PROOF OR NOTHING

you can extend it to numbers above 10, you just need to add another variable to the whole 9 = a+b+c+... thing. And for rational numbers you need to do some shit based on how many decimal places are in the final answer or something

Quote by Pastafarian96
@RedDeath9 - that's exactly how I worked it.


nice.
