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
