How do I use this math symbols keyboard?
Click or tap a symbol to add it to the text box, and type numbers and letters on your own keyboard as usual. When you have finished, press Copy to copy your text and paste it into a document, email or message.
Are there shortcuts for common symbols?
Yes: +- gives ±, != gives ≠, <= and >= give ≤ and ≥, ~= gives ≈, -> gives → and => gives ⇒. For superscripts and subscripts, type ^ or _ before a number: x^2 gives x² and H_2O gives H₂O. ^o gives the degree sign °.
