# GRE Algebra

Just like the arithmetic questions on the GRE, the algebra questions tend to be straight-forward. But again, don't let that fool you! There are many subtle tricks that the GRE makers can throw your way in an attempt to see if you really know the material. To do well on the GRE algebra questions, you'll have to first have a firm grasp of the arithmetic concepts that are used. Not quite sure what absolute value means? What about negative integers? And what about the fact that 2^{2} and (-2)^{2} both equal 4? If you need to brush up on the arithmetic concepts, review the arithmetic tutorial and finish all of the arithmetic practice questions.

Algebra questions on the GRE will involve analyzing and manipulating **algebraic expressions** and solving **first-order** and **quadratic equations**. Not only should you know what these terms mean, but you should understand how to apply these concepts. Algebra is what allows you to make and infer **relationships** between numbers and objects, and many of the math questions on the GRE will require you to set up an equation to solve a word problem. Not only do you have to be familiar with the definitions of these algebra terms, but you must be confident in juggling with variables and setting up the required relationships.

The following concepts are detailed in the Algebra tutorial section:

- expressions
- linear equations
- higher order equations
- inequalities
- simplifying equations
- positive/negatives
- plug and test method
- quadratic equation
- adding equations
- using your scratch paper.
