People add numbers in their heads all the time, even when they're not aware of it. It turns out that math is inescapable and a part of every day life. With 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, and find out about special terms used for numbers in equations. "Math Mania!" boxes allow them to solve problems themselves and assess their understanding of each concept. They'll love "adding" to their math knowledge with this fun book.
