## Introduction to Arithmetic Operators in Python

The special symbols in python to carry out arithmetic or logical computation are called operators, or to perform operations on values and variables, we use operators in python. Individual items can be manipulated using operators and the results can be returned. The data items are known as arguments or operands or the operator operating on the value is called an operand. Either keywords or special characters represent the operators. For example, keywords ‘is’ and ‘is not’ is used for identity operators or 2+3 = 5, in this expression the operator is ‘+’ and it performs addition, operands are 2 and 3 and 5 is the output of the operation.

### Different Arithmetic Operators in Python

Various arithmetic calculations like addition, subtraction, multiplication, division, floor division, modulus, exponent, etc. can be performed using arithmetic operators. Various methods like eval function, call functions, declare the variable and calculate, etc. can be used for arithmetic calculations in python.

The arithmetic operators in python are:

#### 1. ‘+’

The ‘+’ operator is used to perform addition. Two operands can be added using ‘+’ operator.

**Syntax:**

`x ‘+’ y`

Let’s take a simple example in which we will add two digits using ‘+’ operator. The two digits are the operands.

`x = 4`

y = 5

print(x+y)

**Output:**

In the above example, x and y are the operands, ‘+’ is the operator and 9 is the output.

#### 2. ‘-‘

The ‘-’ operator is used to perform subtraction. Two operands can be subtracted using ‘-’ operator.

**Syntax:**

`x ‘-’ y`

Let’s take a simple example in which we will subtract two digits using the ‘-’ operator. The two digits are the operands.

`x = 5`

y = 4

print(x-y)

**Output:**

In the above example, x and y are the operands, ‘-’ is the operator and 1 is the output.

#### 3. ‘*’

The ‘*’ operator is used to perform multiplication. Two operands can be multiplied using ‘*’ operator.

**Syntax:**

`x ‘*’ y`

Let’s take a simple example in which we will multiply two digits using ‘*’ operator. The two digits are the operands.

`x = 4`

y = 5

print(x*y)

**Output:**

In the above example, x and y are the operands, ‘*’ is the operator and 20 is the output.

#### 4. ‘/’

The ‘/’ operator is used to perform division. The left operand is divided by the right operand. Two operands can be divided using ‘/’ operator.

**Syntax:**

`x ‘/’ y`

Let’s take a simple example in which we will divide two digits using ‘/’ operator. The two digits are the operands.

`x = 4`

y = 2

print(x/y)

**Output:**

In the above example, x and y are the operands, ‘/’ is the operator and 2 is the output.

#### 5. ‘%’

The ‘%’ operator is used to find out the remainder of the division when the left operand is divided by the right operand. The remainder of the two operands can be found using the ‘%’ operator. The ‘%’ operator is called the modulus operator.

**Syntax:**

`x ‘%’ y`

Let’s take a simple example in which we will find out the reminder of two digits when one digit is divided by the other using ‘%’ operator. The two digits are the operands.

`x = 4`

y = 2

print(x%y)

**Output:**

In the above example, x and y are the operands, ‘%’ is the operator and 0 is the output.

#### 6. ‘//’

The ‘//’ operator is called the floor division operator. The results of division operation are converted into the whole number by adjusting the number to the left in the number line using floor division.

**Syntax:**

`x ‘//’ y`

Let’s take a simple example in which we will divide two digits and apply floor division ‘//’ operator. The two digits are the operands.

`x = 5`

y = 2

print(x//y)

**Output:**

In the above example, x and y are the operands, ‘//’ is the operator and 2 is the output. The actual output of the operation is 2.5 but as we have applied floor division, the number before the decimal point is adjusted to the left in the number line and the output is 2.

#### 7. ‘**’

The ‘**’ operator is called the exponent operator. One operand raised to the power of

another operand is the functionality of exponent ‘**’ operator. Its left operator raised to the power of the right operator.

**Syntax:**

`x ‘**’ y`

Let’s take a simple example in which we will divide two digits and apply floor division ‘//’ operator. The two digits are the operands.

`x = 2`

y = 2

print(x**y)

**Output:**

In the above example, x and y are the operands, ‘**’ is the operator and 4 is the output.

### Example to Implement Arithmetic Operators in Python

Let’s take a simple example to understand all the arithmetic operators in a python program by including all of them in a single program below:

**Code:**

`x = 15`

y = 4

print('x + y =',x+y)

print('x - y =',x-y)

print('x * y =',x*y)

print('x / y =',x/y)

print('x // y =',x//y)

print('x ** y =',x**y)

After running the program, the snapshot of the output of the above program is shown below verifying the output given in the program. ‘#’ symbol at the beginning of the line in a program indicates comments.

The values for x and y operands are 15 and 4. The output of addition is 19, the output of subtraction is 11, the output of multiplication is 60, the output of division is 3.75, the output of floor division is just 3 and the output of the exponent operator is 50625.
