Mathematical systems consist of … Definitions –“Well defined” & consistent –Common vs. Mathematical meaning Terms are not always descriptive. Examples: –Rational (able to reason) vs. Irrational (lacking the power to reason) –Real (existing, genuine) vs. Imaginary (exists in the imagination only and therefore does not exist)

Mathematical systems consist of … Definitions Axioms –Properties that are accepted to be true but cannot be proven or disproven with previous definitions, axioms, or theorems (i.e. accepted truths). –Examples: If a = b and b = c, then a = c. (transitive) Two points determine a unique line.

Mathematical systems consist of … Definitions Axioms Theorems –Statements that can be proven with previous definitions, axioms, and/or theorems. –Examples: The Pythagorean Theorem You cannot divide by zero..9999… = 1
