Mathematical formulas in HTML 4

Many mathematical (physical, chemical) formulas can be written in plain HTML 4 without resortingSymbol font or to graphics. The symbols below can be displayed on both Mac OS 9 and MS Window possible, place the characters one after another rather than on top of each other. For example, write2 ⁄ 3 [twothirds], A¯ [closure of A], A° [interior of A], (SO4)2− [sulfate ion]. You may want to read also a more detaileddiscussion.To change fonts quickly, choose among different style sheets in your browser:Cambria, Century Schoolbook, DejaVu Serif, Georgia, Times (New Roman).
