How do you work out this question:
Ravi had 237 marbles more than Elliott had. Ravi gave Elliott 165 marbles. Who had more marbles in the end? How many more?
Ravi had more marbles because if he gave Elliot 165 then you subtract 237-165 which is 72 which means now Ravi has less marbles but he has more then Elliot and now he has 72 marbles more then Elliot
