The death of calculator market?

[Thomas Radtke]

This year I worked as a teacher. My students had cheap TI and Casio calculators and didn't master PEMDAS on them. Correct formula, bad result. In the last few weeks I used my calculator to design tasks where they don't need calculators at all. Wise decision.

But: They do liked them. They liked them so much they even used them to solve most simple calculations. Took some time to get them to reckognize they're faster doing some steps in mind.

In physics, calculators are much more important (due to real world data, e.g. measurements). But then we often used the PC room.

I think we can live without pocket calculators.
