Math Symbol Writer

Enter-to-Confirm (recommended) Turn off to convert live as you type.

Type math using plain-text commands (for example: alpha, x^2, a//b, sqrtx, <=, sum i=1..n). The writer automatically turns those commands into symbols (Greek letters, superscripts, subscripts, fractions, square roots, and more). With “Enter-to-Confirm” on, press Enter to convert the last command into formatted math; with it off, symbols appear live while you type and Enter just adds a new line. Use the Copy buttons to paste your formatted math into documents, homework, or slides.

Enter converts the latest command; if nothing matches, it inserts a newline.

e.g. alpha → α, OMEGA → Ω. Also: to → -->

Ops & constants
