Definition
The arithmetic average.
A number that represents repeated multiplication of the same factor.
Parenthesis, exponents, multiplication and division moving left to right,
and addition and subtraction moving left to right.
A function consists of: 1) a set called the domain containing numbers
called inputs, and a set called the range containing numbers called
outputs; 2)a pairing of inputs with outputs such that each input is paired
with exactly one output.
