Adding all of those numbers together should give you the same number you started with.</w:t></w:r></w:p><w:p><w:pPr><w:pStyle w:val=\"text\"/><w:jc w:val=\"left\"/></w:pPr><w:r><w:t>The example she gave us all in class was that extended form of 10,234 is 10000+200+30+4, so you don't need to worry about writing out \"0000\" for the thousands place. All the numbers will be positive, since we aren't supposed to know about negative numbers yet.

Well, that's just the cutest problem description ever. :) And looking at the test suite, your teacher's giving you some mighty big numbers to work with for what (going by the tags) is third grade!
