Discrete Structures : Onto and One-to-one - Prove or disprove (find a counterexample) : If A C B and f : A --> B is an onto function (the range of f is all of B), then f is one-to-one and A =B.

Discrete Structures - In basic algebra the following Theorem is used frequently.
If x,y and z are any three real numbers and if x + z = y + z then x = y.
The analogous statement for sets would read: Let A, B, and ...
Mathematical Induction - Prove that 2(2^n-1) = (n+1)/1 + ... + (n+1)/n for every natural number n.
Discrete Structures - Define and Prove - Use words to describe the solution process. No programming.
