Answer 1

Line 4:
- Indentation error, should be at the same indent level with __init__()
- Method name should be __add__() with double underscores

Line 5:
- Empty line should be removed

Line 6:
- Line should be properly indented as body of __add__() method

def __init__(self, balance):
self.balance = balance
def __add__(self , other):
return BankAccount(self.balance + other.balance)

Answer 3

These are called 'dunder' methods.
dunder as in Double UNDERscore.
for operator + use '__add__' method like this
