## Python Arithmetic Operators

Python Arithmetic Operators perform the usual arithmetic operations like addition, subtraction, multiplication, division, etc. In python, arithmetic operators are in three forms. These are

**Unary Operators -**These work on a single operand.**Binary Operators -**These work on two operands.**Ternary Operators -**These work on three operands. These are the conditional operators.

## Python Unary Arithmetic Operators

Operators | Operations | Examples |
---|---|---|

Unary plus (+) | It gives the value of the operand | Let x = 15 Then +x means 15 Let x = -15 Then +x means -15 |

Unary Minus (-) | It results in the negated value of the operand | Let x = 15 Then -x means -15 Let x = -15 Then -x means 15 |

## Binary Arithmetic Operators

Operators | Operations | Examples |
---|---|---|

Addition (+) | Returns the sum of operands | 1 + 2 = 3 5.0 + 3 = 8.0 2.5 + 3.5 = 6.0 "A" + "B" = "AB" [5,6,7] + [8,9] = [5,6,7,8,9] (1,2,3,4) + ('Bus','Truck') = (1,2,3,4,'Bus','Truck') |

Subtraction (-) | Subtracts the 2nd operand from the 1st operand | 6 - 5 = 1 1.0 - 3 = -2.0 2.5 - 3.5 = -1.0 |

Division (/) | Divides the 1st operand with 2nd operand and returns the quotient | 10 / 4 = 2.5 10.0 / 5 = 2.0 1.0 / 0.3 = 3.3333333333333335 |

Modulus (%) | Divides the 1st operand with 2nd operand and returns the remainder | 5 % 2 = 1 10.0 % 4 = 2.0 12.0 % 7.0 = 5.0 |

Multiplication (*) | Returns the product of the two operands | 2 * 3 = 6 -2.2 * 2 = -4.4 6.2 * 4.5 = 27.900000000000002 "Hello"*2 = “HelloHello” |

Exponent (**) | Returns the result as 1st operand raised to the power of 2nd operand | 5**2 = 25 2.5**3 = 15.625 10.5**3.2 = 1852.7027964066515 |

Truncated Division(//) | Divides the 1st operand with 2nd operand and returns the whole part of quotient | 10 // 4 = 2 10.25 // 4 = 2.0 -10 // 6.0 = -1.0 |

If you notice in the above examples, the result of an operation is implicitly type-casted to the type of operand, which is bigger in terms of byte size. For example
