The way you are supposed to do the math problem 7/28 is you put 7 outside the house and 28 inside the house like they did in the beginning, but where they went wrong was when he said he was not going to use the two........ YOU HAVE TO USE THE TWO=http://!So since 7 cannot go into two you make it 28 and what is 28 minus twenty eight 0!! So, 7 goes into 28 4 times not like the gentlemen thought in the video.
