Calculator hub
Pick a calculator, run your math, then send the final expression (and assumptions) into the Notebook for a reproducible record.
Tip: If a result matters, verify it two ways: (1) check units / order of magnitude, and (2) re‑compute using
an alternate formulation (identity, rearrangement, or graph).

How to pick the right calculator
Choose the simplest tool that matches your problem. Then verify your result using a second method (rearrangement, estimate, or a graph) before you depend on it.
- General: quick arithmetic and safe parentheses.
- Scientific: trig/logs/constants and mode checks.
- Statistics: summarize datasets and sanity-check distributions.
- Programmer: bases + bitwise logic.
- Engineering/Complex: unit discipline and representation conversions.
A repeatable workflow (recommended)
- Write assumptions first (units, rounding, known constants).
- Compute once, then re-compute using an alternate approach.
- Record the final expression + result in Notebook so you can reproduce it later.
