MathSark is a lot more than just a calculator, it works as an electronic flash card system and educational toy. The device comes with quizzes that feature eight different skill levels in addition, subtraction, multiplication, division, fractions, decimals, and percentages. The idea is to get kids to learn math even if they don’t like math, by including quizzes in the form of video games with f;ashing lights and sounds. And kids can of course also use the MathShark as a regular calculator. MathShark retails for $40.38.
