Math is a discipline of logic, but for lots of us, it may as well be magic: a force as powerful as it is unattainable. The “math anxious” among us get tripped up by simple calculations — lost in equations and fractions, until math becomes a barrier. But math competence is an everyday essential, from figuring out grocery-store discounts, to giving your kid the right dose of cough syrup, to deciding on a mortgage. Math also propels innovation and discovery. If you’re avoiding math, you’re probably missing out.

On this episode of The Pulse, we explore why math is necessary to our lives and health, how so many of us got alienated by it early on, and how we might improve our skills.
