Pascal's triangle is a triangular pattern of numbers devised in 1653 by the French mathematician, physicist, and philosopher Blaise Pascal (June 19, 1623 - Aug. 19, 1662). The numbers in each row are derived by adding pairs of numbers in the row above it. The number one is tacked on the beginning and end of each row.

The first few rows of Pascal's triangle are shown below; fill in the rest of the triangle on the worksheet. Note that Pascal's triangle is infinite (it goes on forever).
