Answer 4

The second, third and fourth lines in each elif statement are not properly indented. They need to be on the same indentation level as the first line of the statement. Otherwise, they are not part of the elif statement

Answer 5

That's because of the endless loop. After the first calculation, it expects more input because it is still in the while loop. You can use a 'break' to prevent that. Or just enter 'quit':

add
5
6
add
76
9
quit

works perfectly 👌

Answer 6

Now lines 9, 11, 16 etc. need to be indented to be inside of the while loop
