GRE Math: A Rectangle & Parallelogram with Equal Area
Today, we’ll quickly look at how a rectangle and parallelogram can have the same area. In the diagram to the above, the parallelogram and rectangle share a vertex (D), one vertex of the rectangle (E) is on a side of the parallelogram, and one vertex of the parallelogram (C) is on a side of the […]
Two Definitions of Exterior Angle in GRE Geometry
This may come as a surprise, but there is more than one way to classify an exterior angle. You will want to have both of these definitions in mind when dealing with questions on the test since both instances are possible. Don’t worry! It won’t be too difficult to remember. Type I: At each vertex, […]
GRE Math: Solving Quantitative Comparisons
First off, here’s a tricky algebraic QC: 1) x > 3 If you find this puzzling, this article discusses an efficient method for handling such problems. Before we talk about that, a quick refresher on a few basic ideas dealing with equations and inequalities. Intro to Arithmetic Suppose you have an equation, P = Q. […]
Coming Back to Math after Years Away
Suppose you have been away from math for a while, perhaps since Algebra Two and the SAT in high school. After these necessarily evils, you bid it a hasty farewell and gave it the bum’s rush from your entire life. Now, several years later, you have completed a Baccalaureate degree in something, and wish to […]

For younger children, and especially for selfabsorbed teenagers, getting answers wrong can too easily be interpreted as some kind of negative personal message (e.g. “I’m dumb”, “there’s something wrong with me”, etc.) and it becomes a negative frustrating experience. Getting […]
GRE Geometry Diagram Assumptions
What can you assume on GRE geometry diagrams, and what can’t you assume? First, here are a couple of practice questions. 1) Quadrilateral ABCD is a rectangle. 2) What you can’t assume on GRE geometry problems The biggie is: no diagram is drawn to scale. That means — if nothing is specified about the […]
GRE Math: Histograms
First, a practice question about the following scenario. In a survey, 86 high school students were randomly selected and asked how many hours of television they had watched in the previous week. The histogram below displays their answers. 1) Histogram First, a reminder on histograms. Histograms are not simple bar or column […]
