Demons do not live in calculators;Letter
I am still surprised that thousands are spent on computers and yet the cheap four-function calculator is considered dangerous.
The suggestion that the calculator can only be used for many- digit numbers seems to ignore the opportunities offered for learning with a calculator and only reinforces the notion commonly held by children (and adults) that "calculators do it better".
