Operators are special symbols that represent computations like addition and multiplication. The values the operator is applied to are called operands.

The operators +, -, *, /, and ** perform addition, subtraction, multiplication, division, and exponentiation, as in the following examples:

20+32   hour-1   hour*60+minute   minute/60   5**2   (5+9)*(15-7)

There has been a change in the division operator between Python 2.x and Python 3.x. In Python 3.x, the result of this division is a floating point result:

>>> minute = 59
>>> minute/60
0.9833333333333333

The division operator in Python 2.0 would divide two integers and truncate the result to an integer:

>>> minute = 59
>>> minute/60
0

To obtain the same answer in Python 3.0 use floored ( // integer) division.

>>> minute = 59
>>> minute//60
0

In Python 3.0 integer division functions much more as you would expect if you entered the expression on a calculator.
