YOU'VE PROBABLY ALL SEEN EQUATIONS LIKE THIS ON FACEBOOK BUT DO YOU WONDER WHY SO MANY PEOPLE GIVE DIFFERENT ANSWERS? I THINK WE CAN ALL AGREE THAT ONE DRINK = 10 AND ONE BURGER = 5; NOW LOOK CLOSELY AT THE THIRD LINE. THERE ARE TWO BOXES OF FRIES OVERLAPPING EACH OTHER, SO 4 BOXES OF FRIES IN TOTAL. THIS MEANS THAT ONE BOX OF FRIES = 1; THERE ARE THREE THINGS THAT CAN CATCH YOU OUT IN THE LAST LINE... 1. THERE IS ONLY ONE BOX OF FRIES = 1; 2. THE SECOND SIGN HAS BEEN CHANGED TO MULTIPLICATION; 3. THERE IS A LAW IN MATHEMATICS THAT IF THERE IS AN ADDITION AND MULTIPLICATION IN THE SAME LINE, THEN THE MULTIPLICATION MUST BE DONE FIRST (GOOGLE "BEDMAS"); THE CORRECT ANSWER IS THEREFORE.. 1 (FRIES) X 10 (DRINK) = 10; PLUS 5 (BURGER)= 15
