Suppose I make a bargain where on the first day, I put a million grains of wheat on one square of a chess board. On the second day I put half that number of grains on the next square. On the third day the amount halves again. By the time the last square of the board is filled (after 64 days), how much wheat will be on the board? Your answer should have exactly 4 paragraphs. Make sure that the last paragraph starts with the word "sources" and that each paragraph is separated by two new lines.
