Answer 1

first, change the print on line 14 to add_num_deco.
then either wrap the f(i, j) on line 7 in a print. (recommended).
or change the return on line 13 to a print. (not recommended).

Answer 2

because you indented the print(add_num(5,6)) on line 14, the interpreter puts it in the add_num function.

Answer 3

LONGTIE👔 okay! I edited this code and now line 14 isn't intended

. but Still not working .. it's printing none!
