We can do arithmetic operation as we do in mathametics,
so the available operations are as follows:
-
+ - addition
-
- - subraction
-
* - multiplication
-
/ - division
-
% - modulus
-
// - integer division
-
** - exponent
ADDITION (+) :
As you know addidtion is use to add to are more numbers
Example :
3+4 = 7
a = 5 , b = 6 then a+b gives 11
SUBTRACTION (-) :
As you know subtraction is use to subract two are more numbers
Example :
3-4 = -1
a = 5, b = 6 then a-b gives -1
MULTIPLICATION (*) :
As you know multiplication is use to multiplay two are more numbers
Example :
3*4 = 12
a = 5 ,b = 6 then a*b = 30
DIVISION (/) :
As you know division is used to divide two numbers
Example :
12/4 = 3
a = 10, b = 100 then b/a = 10
MODULUS (%) :
Here comes the programming part , the modulus operator is used to get the remainder
when a number is divided by another number
if 5 is divided by 2 we get the remainder a 1
5/2 = 2*2 + 1 : the number after the + is known as remainder and
the % operator is used to get this number
Example :
11 % 10 = 1
55 % 11 = 0
10 % 5 = 0
INTEGER DIVISION (//) :
The integer division is used to get the integer term of the quotient
when a number is divided by other number.
when 5/2 we get the result as 2.5 , but if we use 5//2 we get the result
as 2 , the decimal term is omitted. This is known as interger division
Example :
45 // 7 = 6
77 // 10 = 7
NOTE : the result is not rounded off , if 77/10 = 7.7
then 77//10 gives 7 as the decimal point is omitted
EXPONENT (**) :
The find a to the power b we can use ** as a**b we gives the result as
'a to the power b'
Example :
2**3 = 8
4**2 = 16
8**2 = 64
