Algebra, Functions, and Patterns

Approximately 20%-30% of the GED Math Test is in the area of Algebra. This includes such things as:

• Understanding the language and symbols of algebra.
• Working with unknowns and variables.
• Evaluating, setting up, and solving equations.
• Using squares and square roots.
• Identifying and applying patterns and relationships.
• Using positive and negative integers.
• Using variables and equations to represent information provided in tables, graphs, and written descriptions.

Algebra is mathematics that uses symbols to stand for unknown quantities. It also provides a way to represent a constant relationship between terms. Just like other types of math, algebra involves solving equations or manipulating expressions that contain symbols - generally variables such as xand y. In fact, a word problem in algebra is like a story problem in basic math.

Just like story problems, algebra problems require that students:

• Identify the information they know and decide what information they need to find.
• Decide which operation or strategy to use.
• Solve the problem.
• Check whether the answer is reasonable and answers the question.

Does this sound like the basic four-step problem-solving approach?
