/ — divide operator

1. Definition

Divide operator is inverse of multiply operator.

Operator is not defined for 0 divisor.

Zero dividend:

0 /a = 0

Sum and difference:

(a + b) /c = a /c + b /c
(a − b) /c = a /c − b /c

Double division:

a /b /c = a /(b × c)

Commutativity:

a /b /c = a /c /b
a × b /c = a /c × b

To divide numbers:

7/2;

To divide complex numbers:

(2+i)/(1−i*2);

To engage current result as dividend or divisor:

rslt/2;
7/rslt;

To engage number z in memory as dividend or divisor:

mem[z]/2;
7/mem[z];

To divide numbers z and w in memory:

mem[z]/mem[w];

Division of complex numbers is supported in professional version of the Librow calculator.
