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.
