Mental Mathematics

In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm.

Do you want to become mentally sharper and quicker? Do you want to be able to save time and calculate large numbers on the go while you're shopping or adding up a bill at a restaurant? Do you want other people to notice how you seem to not need a calculator, how you seem like such a genius? If yes, then this audiobook is for you. Mental math is the ability to solve math problems in your head, without the need to write or use a calculator. And it has all of the benefits implied above and much more.
