The problems you solved in the last section were all number relation problems. They all involved comparing two or more numbers. Again, x does not have to be used to represent the second number. It could be used to represent one of the other numbers. We would then have a different set o...
Not all equations can be solved mentally. We now wish to introduce an idea that is a step toward an orderly process for solving equations. Is x = 3 a solution of x - 1 = 2? Is x = 3 a solution of 2x + I = 7? What can be said about the equations x - 1 = 2 and 2x +...

My professor kept giving me problems, and I kept pursuing them. Before long, he was introducing me to problems that had never been solved before and urging me to find new techniques to help crack them.I am now a Ph. D. candidate in mathematics at the Massachusetts Institute of Technology...
“If you answered a question incorrectly, took too long to answer it, or were unsure of how you solved it, circle it. These are the questions that you’re most likely to miss or skip on a test, so these are the questions you'll want to review the most. Generally, to improve your...
A math word problem is a mathematical exercise (such as in a textbook, worksheet, or exam) where significant background information on the problem is presented in ordinary language rather than in mathematical notation. As most word problems involve a nar
