Fraction, decimal, percent — three ways to say the same answer
Besides fractions, results can be shown as decimals or percentages. Exams want decimals, daily life wants percent — flip a tab and the same answer dresses for the occasion.
More than the four basics
Parentheses, square roots, squares, factorials, percentages and sign flips — all mixable with fractions in one expression. Typed the wrong operator? Just press the new one; it replaces the old, no deleting needed.
A calculator that's also an instrument
Turn on the piano calculator and every digit key becomes a note. 1 is Do, 2 is Re, 3 is Mi — do your math and play Twinkle Twinkle on the side.
Memes, animals and the wild, living in your keys
Piano isn't the only voice. Swap a sound card and your keys can play a funny meme, an animal call, or the sound of rain. Operators and the equals key can each wear a different sound — and one tap on record turns your own voice into a key tone. What plays while you calculate is entirely up to you.
Every step, remembered
Every calculation — even every form switch — gets its own history entry. When you need it, copy the whole expression or just the result, ready to paste into homework or a chat.
It opens in your language
The calculator supports more than sixty languages — Chinese, English, Japanese, Arabic and beyond. From global English to local African languages, they are all on board.
