The discussion focuses on finding the 8-digit number represented as $A=20\overline{abcd}13$, which must be a multiple of 2013. Participants are tasked with determining the values of the digits $a$, $b$, $c$, and $d$ that satisfy this condition. The method involves checking the divisibility of $A$ by 2013, which can be broken down into its prime factors. Solutions and approaches to calculate the valid combinations of digits are shared among users. Ultimately, the goal is to identify the specific 8-digit number that meets the criteria outlined in the problem.

more than one solution
 
continuing with Greg's solution

A = 20132013 is one solution other solutions are A + 2013 *100 * n as long as 2013 * n < 10000 so n = 0 to 4 giving 20132013(this is A itself) , 20333313, 20534613,20735913, 20937213.
 
I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
