# I can't understand how this (function?) works

I'm pretty new to Python and I'm going through a starter book. The code isn't written in English so I tried my best to translate, hope you guys understand.
It has this exercise where we calculate the taxes from the user salary:

``````salary = float(input("Enter your salary to taxes calculation: "))
base = salary
taxes = 0

if base > 3000:
taxes = taxes + ((base - 3000) * 0.35)
base = 3000
if base > 1000:
taxes = taxes + ((base - 1000) * 0.20)
``````

My problem is when the input is bigger than 3000, for example, if I run the code with the salary of 5000, the result will be 1100. But when I do the 'same' math on the calculator the result is 700, so I'm lost in here, could someone explain it please?

Alright, let's walk through it with your example of 5000

``````salary = float(input("Enter your salary to taxes calculation: "))
base = salary
# base = 5000
taxes = 0

if base > 3000: # base is larger than 3000, so we enter the if statement
taxes = taxes + ((base - 3000) * 0.35)
# taxes = 0 + ((5000 - 3000) * 0.35)
# taxes = 0 + 700
# taxes = 700
base = 3000 # base is set to 3000
if base > 1000: # base was set to 3000 in the line above, so we enter the if statement
taxes = taxes + ((base - 1000) * 0.20)
# taxes = 700 + ((3000 - 1000) * 0.20), remember taxes is already 700 from above
# taxes = 700 + 400
# taxes = 1100
``````

since it is two `if` statements and not an `if` and an `else` we evaluate both statements when `base` is set larger than 3000. I hope that helps.
