Calculator reviewer — mathematics
T. Okafor reviews the mathematics calculators, verifying algebraic correctness and, just as importantly, behaviour at the edges — division by zero, undefined results, and the floating-point cases where a formula technically returns a number that should be reported as undefined. Every test case is recomputed independently rather than taken on trust.
What review means here
A reviewer is not the author. Before a calculator is published, the reviewer independently recomputes its worked test values, checks that the formula implemented matches the definition the page claims for it, and confirms the page is explicit about what it does not account for. Where a value is not definitional, the reviewer checks that a source is cited rather than assumed — and if one cannot be found, the calculator is dropped rather than guessed.
