Quick help

How do I add or switch tabs?

Tap ＋ in the tab bar to add a tab. Swipe the display left or right, or tap a tab, to switch.

How do I use one tab’s result in another?

Tap Tab above the keypad and pick a tab. Its result is inserted as a linked chip and stays up to date.

How do I rename, share or close a tab?

How does % work?

200 + 10% = 220, 200 − 10% = 180, and 10% × 200 = 20.
