**Back in school, you learned several useful skills that have greatly benefited you throughout your entire life. English, economics, and science, for example.**

**But what about mathematics?**

**It is probably one of the skills we learned at school that we use most frequently in everyday life. Shopping, paying, following a recipe, most things require a bit of math. However, unless your profession involves complex calculations, most of the math in our lives is pretty simple and easy to solve.**

**But the best part about math problems is that they also are fantastic brainteasers.**

To keep your body sharp and healthy, we must exercise it regularly.
