Description People add all the time in their heads; it's second nature to them. It turns out math is inescapable, even out of school. In this invaluable volume, young mathematicians will be guided through some "fast facts" of addition and learn how they can be applied to real-life situations. They'll find out about the associative, commutative, and distributive properties, as well as about special terms used for numbers in equations. Math Mania! boxes allow them to solve problems themselves and assess their understanding of each concept.
