# Easy Math with Python

Simple math with python , is as easy as counting your fingers ;0)

Basic operations : The reference are been linked to wikipedia

 a+b $a + b\,$ addition a-b $a - b\,$ subtraction a*b $a \times b\,$ multiplication a/b $a \div b\,$ division a//b $a \div b\,$ floor division {only in Python 2.2 and higher versions} a%b $a \bmod b\,$ modulo -a $-a\,$ negation abs(a) $|a|\,$ absolute value a**b $a^b\,$ exponent sqrt(a) $\sqrt{a}\,$ square root

To use sqrt( ) , we need to explicitly import the function , to do so we follow this :

from
math import sqrt

You can also use the round () as , round( the number , number of decimal places to be rounded)

Examples :

>>> from math import sqrt

>>> sqrt(9)
3.0

>>> 3+5
8

>>> 5-6
-1

>>> -0
0

>>> 6*8
48

>>> 1**2
1

>>> 2**1
2

>>> 2**2
4

>>> 2/3
0

>>> 3/2
1

>>> 0/0

>>> 6/8
0

>>> 6//8
0

>>> 7/3
2

>>> 7//3
2

>>> .6/.2
2.9999999999999996

>>> .6//.2
2.0

>>> round(2.9,10)
2.8999999999999999

>>> 22/7
3

>>> 22 // 7
3

>>> 22/7
3

>>> 3.45 * 5
17.25

>>> 4-5
-1

>>> abs(-9)
9

>>> 9%7
