Some simple BASIC programming help, please.

A friend of mine, who does not have Internet access, needs help in writing

a simple BASIC (QBasic) program. She either needs help on what to do in it,

or someone to actually write the program.

She wants a program that tests your knowledge in mathematics. At the

beginning, there will be easy questions. She wants levels of difficulty that

a user can choose from at the beginning, corresponding with the difficulty of

mathematical operations (e.g. addition at level 1, and brackets, exponents,

etc. at the final level, 5).
