<br/><br/> "Addition and subtraction are foundations of elementary math; continuous practice yields proficiency in both. This valuable volume helps young mathematicians hone their subtraction skills while reviewing important strategies that aid in teaching them how to subtract in their head. They'll also practice using this math operation in one- and two-step word problems, which stress that subtraction is used in everyday life. Math Mania! boxes allow readers to apply what they've learned, and provided answers allow for self-assessment."--Amazon.com.
