• buscalc_time_duration

  Find time between two clock readings, including an explicit end-day offset and optional excluded minutes. Use this tested BusCalc worksheet when the task matches its inputs and scope. Returns named results, units, formula, assumptions, method version and a source-page URL. No pri

• buscalc_decision_feasibility

  Evaluate a job, restaurant production run, delivery route, equipment purchase or staffing plan against explicit cost, capacity, earnings and timing limits. Return favorable/unfavorable feasibility, breaking points, permitted repairs and verification priorities. Zero permitted cha

• buscalc_probability

  Calculate probabilities, tails, percentiles, event relationships, Bayes updates, counts, expected values or Wilson/exact proportion intervals using one of 26 explicit methods. JSON numbers only; decimal probabilities. No distribution fitting, random simulation or real-world guara

• buscalc_statistics

  Summarize 1–1000 numerical observations or fit unweighted least-squares y on x from 2–100 paired rows. Returns named descriptive results or slope, intercept, correlation, R squared and a prediction. No causal inference or time-series forecast. Inputs are structured JSON arrays, n

• buscalc_linear_algebra

  Solve numerical quadratic/linear equations, solve a small linear system, multiply or transpose matrices, or compute a determinant/inverse. Structured JSON matrices up to 8×8; singular or unreliable solves are rejected. No arbitrary code, symbolic algebra or unbounded optimization

• buscalc_unit_checks

  Convert compatible length, area, volume, mass, time, speed, force, pressure, energy, power, temperature or angle units. Check dimensions of two explicit products without evaluating arbitrary formulas. Offset temperatures are forbidden in products; money conversion is unavailable.

• buscalc_financial_mathematics

  Calculate NPV from2..601 time-zero-first cash flows, present/future value, beginning/end annuities or equivalent annual value over up to600 whole periods. Explicit ratePercent inputs; unsupported overflow/underflow is rejected. Returns a calculation receipt with inputs, results,
