The python: arithmetic operators

# Arithmetic operators 
A =. 9 
B = 2 

# operators: +, plus, the two objects refers to the sum, a + b output 
Print ( '+ B = A', a + b) 

# operator: - Save to give a negative number, or a number subtracted from another number, ab output 
Print ( 'ab & =', ab) 
Print ( 'B - = a', B - a) 

# operators: *, by , multiply two numbers or return a string is repeated several times, a * b output 
Print ( 'B = a *', a * b) 

# operator: /, in addition, a means is divided by B, a / b output 
Print ( 'a / b =', a / b) 

# operator:% modulus, returns remainder of the division, b% a output 
print ( 'b% a =' , b% a) 

# operator: **, power, power return x to y, a ** b output 
Print ( '** a = B', a ** b) 

# operator: //, take divisible, taken down 's closest integer, a // b output 
print ( 'a // b =' , a // b)
