How many entries in the 100th row of Pascal’s triangle are divisible by 3? By 5? When you divide a number by 2, the remainder is 0 or 1. Color the entries in Pascal’s triangle according to this remainder. You get a beautiful visual pattern. Can you explain it? Can you generate the pattern on a computer? What about the patterns you get when you divide by other numbers? When you divide a number by 3, the remainder is 0, 1, or 2. Divide the entries in Pascal’s triangle by 3 and color them according to their remainder. Can you explain your picture?
