# Thursdays With Ron: Combining Inequalities

by Manhattan Prep, Jun 4, 2010

This is the second installment of our Thursdays with Ron posts. Every other Thursday, our instructor Ron Purewal (known on the Beat the GMAT forums as lunarpower) hosts a free study hall session, where anyone can submit questions ahead of time and attend. Ron chooses a few themes from the questions he gets and goes over strategies for them.

In this recording, Ron goes over Combining Inequalities.

Here's an outline of what Ron covers, with the minute markers parenthesis. Make sure to watch the video, though, so that you're able to follow along!

• Can I add inequalities? (00:12) Ron polls the class to see whether you can add three different sets of inequalities.
• In Real Life Terms: (1:39) Ron explains whether you can add the sets of inequalities he polled the class on by using examples from real life.
• The Rule: (2:52) You can only add inequalities if the alligators face the same way. (Ron explains what an alligator is)
• What do I do if the Alligators dont face the same way? (5:50) Make them face the same way! Ron explains how.
• The other way to combine inequalities: (9:45) connecting the links in a chain.
