In 20 years the most popular book will be titled: "How to think without a computer"

Are there currently books like "How to do math without a calculator"?

There are tons of books explaining how to do math with an abacus, so yes

An abacus is a calculator. Some would say the abacus was one of the first analog computers.

Huh... I suppose it is a mechanical calculator!
