The Basic Operations
Build Your Basics
Understanding (not just memorizing the steps!) the four basic mathematical operations (addition, subtraction, multiplication, and division) provides a strong foundation for the math skills you need for the GED.
STEP 1: Watch the Virtual Class Video and Take Notes
The four basic mathematical operations are:
Addition and its inverse, subtraction
Multiplication and its inverse, division
In order to master the algebra that is the primary focus of the GED, it is crucial that you know:
Each operation's inverse
The various operands or symbols mathematicians use to signal the basic operations
The vocabulary words sum, difference, product, and quotient
Watch the Virtual GED Class video below for a complete explanation and tons of worked example problems.
STEP 2: Complete ONE Level of Practice
BEGINNER
Practice identifying the four basic operations and their inverses and writing simple arithmetic expressions. No variables.
EXPERIENCED
Practice identifying six operations and their inverses and writing simple algebraic expressions with variables.
ADVANCED
Students with extensive exposure to algebra can deepen their understanding of the basic operations by writing and simplifying more complex algebraic expressions.
