Division for Discrete Numbers
Symbols used to express Division:
 a/b , a

widely used by computers and of different

countries.
b
pronounced: “a divided by b” or “a by b”. “a over b”
 :

is only accepted in basic operations, such as in basic
calculators.
Not accepted in English language, except for ratio ( a:
b).
\

used in some mathematical software, such as GNU Octave.

They allow the operands to be written in the reverse order
by using the backslash as the division operator: b \ a.

Division Rules
1) Divisor can not be zero

2) If divisor is zero, the result is undefined
3) Division of two divisions follows the following rule:

Where only p can be zero, the rest are all integers.
