Incepand cu versiunea 4.0 a specificatiilor HTML este posibilia afisarea simbolurilor matematice, cu ajutorul unui set de coduri decimale.

Tabela de mai jos va ofera o privire de ansamblu asupra valorilor decimale existente in HTML 4.0, insotite de o descriere a lor in limba engleza.

Pentru a utiliza simboluri matematice in blocuri HTML folositi urmatoarea secventa:

&#dec;
unde “dec” este una din valorile decimale specificate mai jos.

!!! Simbolurile de mai jos nu vor fi afisate corespunzator in browsere mai vechi de anul 1997 sau in cele care nu suporta HTML 4.0.!!!
