*What is the smallest three-digit number in Pascal's triangle?*

Maybe I'm not understanding the question, because there's only one three-digit number in Pascal's Triangle.

The third row, to wit: **1-2-1** That's reading horizontally, of course... it would be a stretch to assume otherwise.

I agree with the other answer, this question is a tad confusing.

If we interpret it as each number being a number instead (weird sentence, I know), 100 would actually be the smallest three-digit number in Pascal's triangle. It is the second number in the 99th row (or 100th, depending on who you ask), or \(\binom{100}{1}\)

1 15 **105** 455 1365 3003 5005 6435 6435 5005 3003 1365 455 105 15 1 = R 15

Row 15th has 105 as the 3rd combination. But, as Anthrax says, the 2nd combination in the 100th row is 100 and it begins like this:

1 **100** 4950 161700 3921225 75287520 1192052400 1 6007560800 18 6087894300 190 2231808400 .........etc,
