Reviewer Comments:

This exercise attempts to cover quite a bit of territory with some success. The problems on addition and multiplication of signed numbers are straightforward, though some confusion is likely to arise when order of operations are introduced without warning. The explanation of "reversing operations" to solve equations is much too brief and will likely leave the student confused. Finally, this exercise includes references to chapters of a book, making it fail to stand alone.
