Answer 1

If you're asking about operator precedence, you can find the list here:

https://docs.python.org/3/reference/expressions.html#operator-precedence

Answer 2

3**2 = 3 to the power of 2 = 9

So, 3**2//4 - -1 becomes 9//4 - -1 which is simply 9//4 +1

9//4 = quotient when 9 is divided by 4 = 2 as 9 = 4*(2)+1

So, result = 2 + 1 = 3.
