Suppose a1 is the first digit (after the decimal point) of Pi, a2 is the second digit, and so on... What would the following formula equal: (a1 - a2) * (a2 - a3) * (a3 - a4) * ... * (a99 - a100) please help, can not figure this out

Answer:
The answer is zero. Here is the numerical value of Pi to 50 decimal places: 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 Notice the consecutive 8's at the 34th and 35th place? Which means that (a34 - a35) = 0. So the entire product (a1 - a2) * (a2 - a3) * ... (a99 - a100) = 0 Edit: I also noticed consecutive 3's at the 24th and 25th place :)
