Calcumber Math Journal

Do math where you write!
Calcumber Math Journal calculates directly inside Microsoft Word — no switching, no extra tools.

What it does

  • Inline calculations: Write expressions in Word and get the result in place.
  • Units & conversions: Use units (m, s, N, J, kWh, yard, lb, psi, year, day, …) and convert automatically; dimensional consistency helps avoid mistakes.
  • Variables & dependencies: Define variables once and reuse them—changing inputs updates dependent results.
  • Scientific math: Arithmetic, powers/roots, trigonometry, degrees/radians, complex numbers, and common constants.
  • Reproducible documents: Keep narrative, images, and math together in one Word file for clear, auditable work.

Who it’s for

Everyday users: split a restaurant bill, convert units, or quickly check 35 * 77 / 2 without leaving your document.

Students & Teachers: keep problem and solution, explanation and calculation together in one place.

Engineers: write lab reports, assignments, specs, and technical notes while staying in Word for math.
