Pöytälaskin Casio MS-120FM peruslaskin musta 12 numeroa vero voitto

The Casio MS-120FM is a basic desktop calculator with a 12-digit display designed for business use. It supports cost, selling price and margin calculations as well as tax and profit functions. The unit runs on solar power when light is sufficient and switches to battery power when needed. A metal faceplate and a rounded, ergonomic body give the calculator a professional appearance suitable for office environments.

Advantages

The extra large 12-digit display shows clear numbers for accurate, error‑free calculations. Keys are arranged and shaped to match natural finger movement, and each key includes a shock‑absorbing structure for a comfortable two‑step touch that reduces finger fatigue during prolonged use. Function command signs (+, −, ×, ÷) appear on the display to indicate the current operation. Color-coordinated keys and a metal faceplate combine visibility with a refined look.
