>We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).

I suppose it depends if you took advanced math classes or not.

My high school required one for a math curriculum that was specifically designed with the idea that students would not need advanced math classes. It kids up for failure if they were hoping to move toward higher level math in college, as the fundamentals were never adequately taught. But at least they sold thousands of calculators to kids who would never use them again.

They actually started us on them in 7th or 8th grade.
