you both can buy me lunch. The answer is 28.
restate the question as: subtract negative 20 from 8
Mathematically, this is the same as "add 20 to 8."

you go dutch....you're both wrong - the answer is 28. 8 minus negative 20 = 8+20 = 28

Both of you should pay for your lunch.
8 -(-20)=
8 + 20 = 28
The parenthesis is not a multiplication but a mere separtion of signs.

There is a very simple rule (don't they teach it any more?)
'Two minuses make a plus'
Also
'A plus times a plus is a plus, a plus times a minus is a minus, a minus times a minus is a plus'
'A plus divided by a minus is a minus, a minus divided by a minus is a plus, a minus divided by a plus is a minus'
