## What is YYi Calculator?

Personalize your calculator with rich themes and keep every calculation organized in tabs.

Explore powers, roots, logarithms, trigonometry, constants, random values, memory, and parentheses. Organize work in tabs, reuse any past number, and see each tab’s total and average.

Live formulas remain visible until you calculate, and the interface adapts to portrait and landscape
