Pieces of Pascal:
A Website All About Blaise Pascal and Pascal's Triangle

 Welcome to Pieces of Pascal! Pascal's Triangle is constructed by addition. The top of it can look like this: The one is the top number. The top one has zeros on both sides of it, but those zeros are invisible. One plus the left zero equals one; put that sum below the two addends (and in between them). Repeat that process for the right side. Now, you have 0110. 0 + 1 = 1. The 1 plus 1 equals the two, and 1 + 0 = 1. So now, you have 01210, and 0 + 1 = 1, plus 2 is three. You can now do the same for the right. You have 013310. You can keep adding to the riangle forever. When you make the triangle, do not add the zeros. Now think of a three at the top of the triangle. 3 + 0 = 3, 3 + 0 = 3. You now have the first row. Keep adding 3 more rows. Does your triangle look like this? Try making this triangle with a two at the top. Does it still work?
