Yea. It sets up cell 1 as 90 for the ten's place and cell 2 as 9 for the one's place, then does a few functions that subtract ten's places if theres no one's place, and sets the one's place back as 9. Then it starts putting out the text and the values of cell 1 and 2 and singing '99 bottles of beer on the wall, 99 bottles of beer take one down pass it around 98 bottles of beer on the wall' etc. You can slow it down and go step by step by putting a comma after the last decimal and before the '[-]' on the very last line. and just hit enter to keep going. I did run the program to see the text, but up till that part I kind of figured out how the program worked. Im not exactly sure about it all though.
