We Don't Need No Stinkin' Algorithms

An industrial mathematician is upset about the way math is being taught:

The claim that schools that have done away with traditional mathematics instruction have done so because they want "to prepare kids for a new world" is ridiculous for many reasons. The most important is that the job of math educators is to get students to understand math, and the best way to understand math is to master the traditional algorithms.

There are a lot of ways to teach algorithms... but... not to teach them at all?

There are no rules
in schools for fools.
