Addition

Addition in Python is easy - just use "+" sign. You can add numbers or variables (or mix of numbers and variables).


              1234
            
a = 1
b = 2
c = a + b
print(c)

Sometimes people use alternative operator: "+=" (it is typically used for brevity). Please see example below (this basically means "increase variable on the left hand side by 1"):


              123
            
x = 100
x+=1
print(x)

Task

Add line to print the sum of 20 and 22.
