'Greater than or equal to', as the suggests, means something is either greater than or equal to another thing. 'Greater than or equal to' is represented by the symbol ' (geq)'. This symbol is nothing but the 'greater than' symbol with a sleeping line under it. We know that (8) is greater than. A greater than or equal to sign looks like a greater than sign placed over the top of an underscore. Microsoft Word 2007 offers Unicode hex numbers and shortcut key combinations to produce this sign just as it looks in a math book.
Mac OS has a rather useful built-in utility called the Keyboard Viewer – an onscreen keyboard that displays many of the possible symbols. To Activate the Keyboard Viewer: 1. Open System Preferences- Keyboard. Tick the box labelled Show Keyboard and Character Viewers in menu bar.
