    I don't quite understand you, Sharmane. Both you and Salifian are correct in your answer. Could either you or Salifian care to explain more clearly to me?

    Tom __________20
    Jerry __________
    After
    Tom __________
    Jerry __________20

    Now Jerry has 20 more marbles than Tom

    Tom _________
    Jerry ___________20

    Tom gave Jerry 8 marbles.Jerry has 16 more marbles.20+8=28#
    If Tom throws away the 8 marbles,Jerry has 8 marbles more.
    But now,Tom gives the 8 marbles to Jerry,as a result Jerry has another 8 marbles more.
    The 20 marbles + the 8 marbles Tom gives Jerry
    =36.

    Sounds clear enough to me. Good job Salifian.
    Anyone else has another way to explain the answer?
