"Several of our classes involve students using mathematical expressions, but there was no way for us to automatically check this work. The stated solution to a problem may be x+y, but if a student answers y+x, our system needs to understand that this is also correct." "sympy, an open source Python library for symbolic mathematics," is proposed as a solution.

"Most of these books are beginner level books, simply introducing the concept and terminology. However, there are a few at the end that are really great, and begin to introduce equivalent fractions and even discuss the numerator and denominator."

The Final Report of the National Mathematics Advisory Panel noted that many middle school students have a weak understanding of mathematical equality and that this lack of understanding impedes their learning of algebra.
