OMG this is freaking me out !!

Just follow the instructions, and then be amazed.

if you can work it out ill give you rep

 

All/most symbols change. Edit- nevermind I got this one confused with the other similar game, this one gives the same symbol to the only possible outcomes. I'm no pupil of maths but there will only be a very small number of possibilities and I guess it sticks that symbol to all of them.

 

yeah but how does it still know what the number is

 

Or that you can only get 89, 81, 80, 72, 66, 63, 54, 45, 36, 30, 27, 24, 18, 9 or 0

 

Didn't work for me, got the wrong symbol.

 

Yeh sorry I hadn't gone all the way through the game and thought it was a similar one where it bets you that your symbol disappears or something. Edited my post.

 

then your maths is wrong

 

attempted rep

 

Not really, I picked 56, then you add them together it makes 11, take that away from 56 it makes 45, it gave me an eye symbol instead of the pyramid thing which is what the symbol for that number was.

 

well he got mine wrong, sucker.

edit: i should say that since he just said the symbol 'next to' instead of 'to the right of' like he should have, i exploited the loophole and went for the one on the left of the number i picked.

 

oh well, 56 just worked for me

 

It all due to an anomaly in the 9 times table. Based on the principle that all numbers in the table when you add the digits together total 9 eg 45 - 4+5=9, 63 - 6+3=9. You can make it as elaborate as you like, if you look all the numbers in the 9 times table have the same symbol net to them.

 

10 = 1+0 = 1
10-1 = 9

11 = 1+1 =2
11-2 = 9 so its always 9 for 10 to 19

20 = 2+0 = 2
20-2 = 18

21 = 2+1 = 3
21-3 = 18 so its always 18 for 20-29

all numbers 30-39 will equal 27
all numbers 40-49 will equal 36
all numbers 50-59 will equal 45
all numbers 60-69 will equal 54
all numbers 70-79 will equal 63
all numbers 80-89 will equal 72
all numbers 90-99 will equal 81

so all those numbers will have the same symbol

 

is simple terms (but i like to see workings) it will always be a multiple of 9 so the simple changes next to a multiple of 9 each time.

 

Its this. I did a very similar problem in school after Maths GCSE when no-one really cared what we did.

 

yes that is correct
