Keep your mind sharp all year long with Mathematics: Your Daily Epsilon of Math 2020, a 12" × 12" wall calendar featuring 12 images relating to math concepts! Too often, math is sidelined as a daunting part of academia that we rarely use outside of school; but doing daily mathematics can help keep your brain working in ways that verbal exercises can't. Let mathematicians Rebecca Rapoport and Dean Chung stimulate the left side of your brain by providing you with an equation for every day of the year. The solution for each equation is the date; but the challenge lies in figuring how to arrive at the answer, and possibly discovering more than one method of arriving there. With entry-level algebra, word problems, and math puns thrown into the mix, this calendar allows you not only to do math, but also to see the many ways in which math can be applied to your everyday life. End the year with more brains than you had when it began with Mathematics: Your Daily Epsilon of Math 2020.
