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 operationsThe vocabulary words

**sum**,**difference**,**product**, and**quotient**
