1. 2013 minus its 1 / 2, and then minus the remaining 1 / 3, and then minus the remaining 1 / 4, and so on, continue to subtract the remaining 1 / 2013, find the final remaining number. 2013 * (1-1 / 2) * (1-1 / 3) * (1-1 / 4) *. * (1-1 / 2013) = 2013 * (1 / 2) * (2 / 3) * (3 / 4) *.. * (2012 / 2013) = 1; 2
