Cognidia supports different categories of problems, each with specific requirements on the solution.

• Fact recall problems which require a term or a formula as the answer

• Calculate problem which requires a number as the answer

• Normalize problem which requires simplification of an expression to a standard form

• Solve problem which requires finding the value of one or more variables

• Show problem which requires a proof of an equation or inequality

The Problem Statement will specify the type of problem and the expected form of the final answer.
