The goal of this session, as well as many that follow, is to immerse ourselves in mathematics that illustrates two components of algebraic thinking: mathematical thinking tools (problem solving, representation, and reasoning skills) and algebraic ideas (functions, patterns, variables, generalized arithmetic, and symbolic manipulation).

Key Terms. Proof: A logical argument that uses logic, definitions, properties, and previously proven statements to show a statement is true. Definition: A statement that describes a mathematical object and can be written as a biconditional statement. Postulate: Basic rule that is assumed to be true. Also known as an axiom.

Proof - Higher. A mathematical proof is a sequence of statements that follow on logically from each other that shows that something is always true.

2.1 Direct Proofs. A proof is a sequence of statements. These statements come in two forms: givens and deductions. The following are the most important types of "givens.''. The P P s are the hypotheses of the theorem. We can assume that the hypotheses are true, because if one of the Pi P i is false, then the implication is true.
