Instructions excerpt

Use `calculate` to verify math computations via math.js. `operation` selects `evaluate` (default, numeric), `simplify` (symbolic, with trig identities), or `derivative` (symbolic, requires `variable`). Covers arithmetic, trigonometry, logarithms, statistics, matrices, complex numbers, combinatorics, and unit conversion (e.g. `5 kg to lbs`). Pass variable values via `scope` (e.g. `{ "x": 5 }`) and bound numeric output with `precision` (1–16). One expression per call.
