Keep the method simple
Rounding: keep the requested places and check the next digit. It does not mean always round upward.
Negative substitutions: put the replacement in parentheses and do powers before multiplying.
Statistics: choose the right output. Sx is sample standard deviation; σx describes a full population. Fences are cutoffs; whiskers end at actual non-outliers.
Calculator limits: term counting and symbolic simplification still need reasoning. A TI-84 Plus does not do symbolic algebra automatically.
