im sorry i dont know the solution.... but all i can tell you is it must be a SINGLE digit/..!@#$.....

That's not true, since you're multiplying the millionth digit by 5. If the millionth digit was 6, then 5 times 6 is 30

yes thats true!

Yes 25 is right ans.....

Thing is, according to Wolfram Alpha, the millionth digit of pi is 5. Therefore 5 isn't the right answer. http://www.wolframalpha.com/input/?i=one+millionth+digit+of+pi

Thats assuming that the first digit of $\pi$ is $3$ . This question is assuming that the first digit of $\pi$ is $1$ in $3.\textbf{1}415...$ .

I have to agree that this question is a little ambiguous.

Thanks. I have updated the question to avoid this ambiguity, by stating that the first digit is 3.

I have updated the answer to 25. Those who previously answered 5 are still marked correct, due to the ambiguity of the problem.

@Calvin Lin – Ugh, so... Much... Complications... The sources I saw said it was 1 . I'm probably gonna delete this problem, what do you think?

@Nolan H – According to Wolfram Alpha , the one millionth digit of pi is 5. The surrounding digits are 81513.

They defined the first digit of pi to be 3, and the second digit of pi to be 2. Hence, the way that I originally wrote the question would have led to an answer of $5 \times 5 = 25$ , which is the updated answer.

I have reverted the changes that you made.

@Calvin Lin – I understand that, but when I made the question, I didn't include the 3
