Rapid Math Tricks & Tips: 30 Days to Number Power - Julius, Edward H

Master common math problems without a calculator! Award-winning math teacher Ed Julius covers more than 60 powerful math tips and techniques in his entertaining 30-day program. For example, multiply any two-digit number by 11 simply by splitting apart the two digits, adding them, and placing the sum in the middle (45 x 11 = 495 because 4 + 5 = 9).
