Students should only be permitted use of calculators when they can manually and demonstrably solve the manner of problems for which they’d seek to use them, and/or to check derived answers. Otherwise, the students utilizing them would not be learning, and would fail any formal examination on which they would not be allowed use of calculators.

All students should be distributed and required to memorize multiplication charts; they should not be allowed to utilize them in class, however, unless they are knowledgeable of how to independently derive products from factors.
