Simple math terminology [#permalink] New post 18 Sep 2006, 21:40
This may seem like a naive question, but I want to make sure I know the GMAT terminology exactly.

In word problems, does "difference between x and y" always mean x - y, as opposed to |x - y|.

For instance, "the difference between the length and width of the rectangle is 20." Does that mean the length is definitely longer than the width?

Thanks

My understanding is that the difference between x and y does not imply the use of absolute value unless specified in the question stem.

You can safely assume that length is greater than width.
