Algebra

Words of “Wiz-dom”The algebra on the SAT is not very challenging mechanically. As usual, the difficulty lies in the understanding or reasoning related to the problems. The big challenge is these are word problems that will challenge you in the process of translating words into math operations.  If you need a refresher, refer to the following Word-Math Operation Chart.

You’ll need to be able to simplify a few algebra equations as well as setup and solve some algebra equations. About as difficult as it gets is using two equations with two unknowns and factoring simple quadratic equations. (You won’t need to use the quadratic formula!) To help refresh your memory of the required algebra techniques, we’re going to start with some practice exercises.
