You can solve all the problems with a singular method:
1 = (6) / 6
2 = (6 + 6) / 6
3 = (6 + 6 + 6) / 6
4 = (6 + 6 + 6 + 6) / 6
5 = (6 + 6 + 6 + 6 + 6) / 6
6 = 6
7 = 6 + ((6) / 6)
8 = 6 + ((6 + 6) / 6)
9 = 6 + ((6 + 6 + 6) / 6)
...
The pattern just repeats every 6.
Plato is right, what a garbage problem. Time to go take some names .
I completely disagree with people who sneer at problems of this kind. I think that they can be very effective in helping people to develop mathematical styles of thought. But obviously we can't help with this particular problem unless we know a bit more about it, such as what symbols are allowed (square roots? factorials?) and which numbers are causing particular difficulties.
