Hey everybody,

Came accross this puzzle a few days ago, its very similar to the maths puzzle that showed up in the tgc newsletter a couple of years ago.

Here's how it goes:
Using exactly four 9's and any combination of mathematical symbols, create a equations for each number from 0 to 9
Eg
99-99=0


You may not use any additional numbers in the equation, you must have exactly four 9's. They can all be completed using only mathematical symbols you will have learnt about in highschool.

For those who didn't get to try the old one, it was quite similar.
Using three digits and any combination of mathematical symbols, make each number from 0 to 9 add up to 6
Eg
2+2+2=6


Hope you find this interesting they are all possible so don't give up.

Post your answers here if you like but put them in a code box! (No spoilers allowed)

maths....... maths
You must be from europe.

Le Verdier, I'm not sure your answer for 4 counts :p Using extra variables would make the whole thing too easy. And 8 just seems plain wrong.



4 and 8 were the trickiest.

Ah! My friends and I have been working hard on this all day... I'm surprised some of you are calling 8 hard; I came up with it almost immediately. Here's what I have so far:



Ah, 9s are starting to look like upside down 6s...

I wouldn't say hard I guess. Once I solved it I was like oh it was easy. But it was the last one I figured out. I posted this on facebook and just got a lot of replies of swearing.

Yeah, definitely. It seems a lot of them are like that, 3 for myself. My friend got it a good half hour before I did; he kept telling me it was simple, and when I got it, I was dumbfounded at how simple it indeed was.

It must be difficult to do maths in the US, when you haven't realised there is more than one math
