How far do you want to go?
Are the equations going to be in a fixed format with regard to whitespace, operators etc or do they all have to be coped with.
eg 2X3, 2*X^3
Simple polynomials can be done fairly easily with string manipulation but if you want want trigonometric, log functions etc thats a bit more tricky.
Do you just need a string out or do you need to actually do the maths
