The following extra credit problem can be submitted Tuesday, Sept. 16 at the open house, which is scheduled from 6:00 - 8:00 p.m. If you are unable to attend, I will also accept solutions on Wednesday.
I am a number between 212 and 770. The digits in me descend, like the number 4,321. My digits add up to 12. What number am I?
The correct solution will earn you 2 extra credit points. I need to see some work or a paragraph explaining how you arrived at your answer. A number is not enough. Fee free to ask your family for help. Remember, I will also have other activities available that evening for extra credit.
