Order of Operations

A set of rules used to determine the order in which calculations are performed; represented by PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Linear Equation

Function Notation

A way to denote functions; typically written as f(x) to indicate a function named f evaluated at x.

Congruence

Translation

A transformation that shifts a figure in a straight line from one position to another.

Reflection

A transformation that flips a figure over a line to create a mirror image.

Dilation

A transformation that alters the size of a figure but preserves its shape.

Real-World Applications of Algebra

Application of algebraic principles to solve practical problems encountered in daily life.

Practice Tests

Simulated exams used to prepare for the actual test format and test-taking experience.

Study Schedule

A plan that outlines study sessions to manage studying time effectively.
