Click the buttons or use your keyboard. Numbers, operators, parentheses and functions all build up an expression shown in the display.
2
Use scientific functions
sin, cos, tan, log, ln, √, x², xʸ, 1/x and |x| are available. Toggle DEG/RAD mode for trigonometric calculations.
3
Memory & history
Use MC/MR/M+/M− to store values in memory. The last 10 calculations are saved in the history panel — click any entry to restore it.
