# Python Basics - Numbers

Today, we will be looking at how we can work with Numbers(int, float, complex) 

let's start with int 

int data type refers to integers in mathematics

float data type refers to decimal point numbers 

complex data type refers to numbers with real, imaginary part (generally used for scientific research purposes ) 

```
     a = 22 
     b = 21 
     c = a + b 
``` 
we can perform all the basic mathematic operations on integers like 
 Addition 

 Subtraction
 
 Multiplication

 Division
 
 Integer Division 

 Remainder

power 

You might be wondering what's the difference between division and  integer division  


```
     a = 5 
     b = 2
     c = a/b 
     d = a//b
``` 

now, c holds a value of 2.5 , but d has a value of 2. 

division(/) always returns a float ,whereas (//) always returns an int. 

% - remainder of the division 

** - power 

```
     x = 2 
     y = 7 
     z = y**x
    q = y % x 
``` 

z has a value of 7 raised to the power of 2 (49) , q has a value of remainder of 7/2 that is 1.

All these operations can be performed on Numbers(int, float, Complex)
