Re: INNUMERACY, was Re: Use of Calculators

No one has mentioned the most pervasive calculator error students make.
In their rush to punch numbers into their calculations they often forget
to use ther calculators' memories. It is commonplace to see a student
crank out an intermediate result in a problem, round it off and write it
down, and then punch in the rounded value later on in the problem.

The solution to this is obvious, but it is steadfastly resisted by many.
