About these math

Maths symbols for homework, papers and spreadsheets: operators like ± × ÷, relations ≠ ≈ ≤ ≥, set theory and logic, calculus and geometry.

You get 148 symbols here, sorted into 6 groups: arithmetic (28), comparison (29), sets and logic (37), calculus (23), geometry (14), number sets and constants (17).

They span almost the whole history of Unicode: from version 1.1 (1993) to version 4.1 (2005). The newer ones need an up-to-date phone.

How do I copy math?

Tap a symbol and it is copied. To copy several at once, turn on Collect, tap them in order and press Copy all in the bar at the bottom. Your recent symbols appear above the grid next time.

Why do some math show as boxes?

A box means your device has no font for that character. The oldest symbols here date from Unicode 1.1 (1993) and work everywhere; the newest come from Unicode 4.1 (2005) and need a recent system update.

Where can I use them?

Anywhere you can type text: Instagram and TikTok bios, Discord, WhatsApp, Word, Google Docs, emails and most game chats. A few username fields accept only letters and numbers.
