Integer Operations - A J Thomas - Bog

BLATANT MATHEMATICS: A fusion of visual, auditory, linguistic, and cognitive arts. Beautiful illustrations surround a simple tale that captures the "how to" of basic integer operations. Part 1: Crossroad Encounters demonstrates properties of adding signed numbers. Part 2: A Wavering Wand illustrates subtraction. Part 3: Potions and Poisons shows multiplication and division by positive scale factors. And Part 4: The Mixing of Magics does the same for multiplication and division by negative values. An excellent classroom and home library resource.
