Introduction to Arithmetic Operations

The basic arithmetic operations for real numbers are addition, subtraction, multiplication, and division.

Arithmetic operations can be performed on negative numbers according to specific rules.

A fraction represents a part of a whole and consists of an integer numerator and a non-zero integer denominator.

A complex fraction is one in which the numerator, denominator, or both are fractions, which can contain variables, constants, or both.

Exponential form, written $b^n$, represents multiplying the base $b$ times itself $n$ times.

The order of operations is an approach to evaluating expressions that involve multiple arithmetic operations.
