[quote=Anonymous]Hi, I need to help my son and I do not understand decomposing. I know decomposition, but not this decomposing. Someone please help me! For example - the worksheet my son brought home: For the problem: 698 [u]-327[/u] The sheet asks him to fill in the blanks: _ _ _ -_ _ _ [u] _ _+_ = _ I understand decomposition: 600 + 90 + 8 minus 300 + 20 + 7. I do NOT understand the problem the way the worksheet laid it out. with the two hundreds numbers going to a ten plus a one to equal a one digit? [/quote]
