Video: GMAT Absolute Value

January 5, 2012

Back in middle school, you probably learned how to evaluate an expression that contains a pair of absolute value signs. But can you manipulate an expression when variables are inside the absolute value signs?

When you take the GMAT, the quant section may contain a question or two requiring you to do so. Most students aren't ready.

My latest video covers the basics of absolute value, which will set you ahead of most test-takers. If you want to hone your skills even more, there's a chapter with a drill and test-like practice questions in Total GMAT Math.
