    Roger has 9 white buttons. He has 3 fewer brown buttons than white buttons. Roger has 3 more gray buttons than brown buttons. How many buttons does Roger have in all?

    • 9 white buttons
    • 3 fewer brown buttons than white buttons. So Brown = 9 white - 3 = 6 brown
    • Gray = 3 more than brown = 6 + 3 = 9
    All together:
    9 white + 6 brown + 9 gray = 24 buttons
