Read a formula

Paste a formula, or build it with the symbol pad, and it is read to you in words. The reading is made by fixed rules, so the same formula always gives the same words, and it works without the internet.

Where a formula can be read in more than one way (|x|, (a, b), f(x), the d in dx …) the reader picks one by a rule and shows you the other readings.

The Persian readings are drafts: an AI helper wrote them and no native speaker has checked them yet. If one sounds wrong, tell us.
