you have to do what is in parenthesis so you would add 2 and 12 and get 14 then you would drop everything down and then your problem should look like this:-3(14 times 2)-16-4 then you would need to multiply 14 and 2 and you would get 26.your problem should now look like this -3+26-16-4,then you add negative 3 and 26 and you would get 23-16-4.then you subtract 16 from 26 and then you get 7 so now your problem is 7-4 and you would get 3.
