ASCII codes allow you to type special characters and specific symbols, such as the mathematical symbol of "less than or equal" into programs and documents. The process to be followed to type these special characters varies according to the operating system in use, but is the same for all programs and applications. For example, the method used to insert the "less than or equal" symbol in a Word document is identical to the method used to insert it into a Google Docs file, however the process to follow will be different between Windows and Mac.
