Arithmetic Operators in Python

Arithmetic Operators 

Python does a good job of processing mathematical expressions with its basic arithmetic operators. You can easily make programs to automate tasks such as computing tax, tips, discounts, or rent.

           

+	Addition	adds   the      value  of        the      left      and     right            operands
-	Subtraction	subtracts       the      value  of        the      right   operand            from   the value      of        the      left      operand
*	Multiplication	multiplies      the      value  of        the      left      and            right   operand
/	Division	divides           the      value  of        the      left      operand            by       the      right operand
**	Exponent	performs      exponential  calculation
%	Modulus	returns          the      remainder    after   dividing         the            left      operand with          the      right   operand
//	Floor Division	division          of        operands      where            the            solution         is         a          quotient left            after   removing      decimal         numbers

           

           

Addition,      subtraction, multiplication,         and     division          are      the      most   basic            operators     and     are invoked by       entering        the      following      expressions:

Addition:

           

>>>1  +          3

4

           

Subtraction:

           

>>>10           –          4

6

           

Multiplication:

>>>4  *          2

8

           

Division:

>>>10           /          2

Exponent

           

Exponential  calculation    is         invoked         by       raising            the      first     number         to            the      power            defined          by       the number after   the      **       operator:

           

>>>2**3                                                                                                                                                                  2          raised to        the      power            of        3

8

           

Modulus

           

The     modulus        operator       gives   the      remainder    after   performing  division:

           

>>>17           %         5

2

           

           

Floor  Division

           

Floor  division,        on       the      other  hand, returns          the      quotient        after   removing            fractional      numbers:

           

>>>17           //         5
