- X-stepped calculations
- Molecular calculator command e.g. MCALC(CaSO4)
- Scientific constants

The CHEMIX calculator functions basically in the same manner as a real pocket calculator. Enter numbers or functions either by clicking on the buttons or using the keyboard . The calculator has the ability to calculate 400 Y-values if the
