Numbers and Functions Only

[James]

Does anybody know how you can perform a simple maths equation and read it from inside an input box?

Example,

The number I have to reach is 50. I can only use numbers 1-6 and the symbols +-*/ How can I check my input box for the equation and check it matches the number I have to make..

Example of entering numbers,

I need to make 90:

I will do, 5*6*3=90 I then click Check Numbers and it will check if my equation in the $NumberEntry box has used the numbers 123456 only once and that I have made the number 90 in this case.

Thanks,

-James

Edit: Added example of numbers I need to make.
