What I saw was one man prepared 28 doughnuts for seven officers and he thought he could divide it so that each officer got 13. Witch was…wrong, for it to be right each officer would have to have four. At first he took away the two and put 7 into 8 with the remainder of 1, then put the two back making it 21, witch he was suppose to not take out the 2 and just put 7 into 28. He then divided 21 by 7 that equaled 3 making it 13.Another thing he did was try to add up 13 seven times but he didn’t carry the 2 and he just added the seven ones making it 28. This trick would also work with 25,14,and 5.
