I have been reading The Smartest Kids in the World by Amanda Ripley. Just have to share a paragraph from the book here.
“Math is a language of logic. It is a disciplined, organized way of thinking. There is a right answer; there are rules that must be followed. More than any other subject, math is rigor distilled. Mastering the language of logic helps to embed higher-order habits in kids’ minds: the ability to reason, for example, to detect patterns and to make informed guesses. Those kinds of skills had rising value in a world in which information was cheap and messy.”
