Well... -5+12 you gotta add that first and look for the biggest number that's when you can decide whether the answer is - or + so -5+12= 7 then you add 7+10 which is 17 and then 17-(-7) WAIT (did you know that when a negative sign is besides a subtraction sign you change the subtraction sign for a + and the number is not gonna be negative and it changes into a positive so 17 -(-7) {17+7}= 24 if you doubt use a calculator! HOPE I HELPED! And I was really bad about this too, I just understood today. LOL

-- Take. -5 . -- Add 12. to it. -- To the result, add 10. --- From that result, subtract 7 . -- The current result is the value of the expression.
