# division sign

The division sign resembles a dash or double dash with a dot above and a dot below (÷). It is equivalent to the words "divided by." This symbol is found mainly in arithmetic texts at the elementary-school level. It is rarely used by professional or academic mathematicians, scientists, or engineers.

Mathematically, the division sign is equivalent to the forward slash. Thus, for example, 4 ÷ 5 = 4/5 = 0.8, and -100 ÷ 10 = -100/10 = -10. In general, for any real number x and any nonzero real number y , the following is always true:

x ÷ y = x / y

The division sign is also mathematically equivalent to the ratio symbol, customarily denoted by a colon (:) and read "is to." Thus, for any real number x and any nonzero real number y , this equation holds:

x ÷ y = x : y

On most IBM-compatible computers, the division symbol can be generated by activating the NUM LOCK function, holding down the ALT key, and entering 246 on the numeric keypad located at the right-hand end of the keyboard. The division sign appears when the ALT key is released. This technique works in most word processors, and even in some graphics and DOS programs.
