Arabic mathematical notation

Editing math formulas for arabic scientific texts is far more than allowing Right-To-Left text. WIRIS editor has been developed following W3C Arabic Mathematical notation recomendations.

There is still work to be done. We will appreciate your comments and feedback.

Our Support team is ready to help you in English and Spanish at support@wiris.com .
We cannot give you support in Arabic yet.

Mirroring - RTL mode

Mathematical symbols have to be mirrored to keep their mathematical meaning in Right-to-Left writting (RTL).
 
For example, the Left-to-Right expression x subset of double-struck capital n is shown as Syntax error. if using th RTL mode. Arabic letters are also supported by the system. The former formula would tipycally look like Syntax error..
Other mathematical expressions are mirrored to follow the Arabic notation tradition . For example, in Saudi Arabia a square root like square root of italic س is represented as Syntax error. in RTL mode.

Variables ligatures

Arabic characters, when written together, are typografically joined with the so called ligatures.

In mathematics, variable names are typically formed by a unique character. Hence by default we consider every character a stand alone mathematical variable, and so without ligatures. But we recognize some standard words, and we automatically add ligatures to them. Also you can manually add ligatures, using the button.
