About this printable

A single-A4 printable with cut-apart cards: rule cards that give an operation and f(x) formula (e.g. Add 5, Multiply by 2, Square the input), input cards that state x = (various integers including negatives and zero), and output cards with a blank box and space for y = ___. It is designed to support concrete practice of substitution/evaluation, order of operations and input→rule→output reasoning.
