• ### Automatic vs. on demand

Get automatic conversion and calculation or take the time you need by using calculation on demand.

• ### Display mode

Display the result in decimal, fraction or mixed numbers. Use radian or degree for trigonometry.

• ### Write on several lines

Whenever you lack space when entering a long calculation, just continue on the next line.

• ### Write several calculations

Write several calculations on different lines. Use drag and drop to easily create multi-step calculations.

• ### Drag and drop

Drag and drop numbers from and to the canvas, the memory bar or to an external app.

• ### Memory bar

Drag and drop numbers on the toolbar to store them. Reuse them by dragging them back onto the canvas.
