      Example: 100 x 1000.23 = 100023 . In this case, according to the significant figure rules for zeros, in the 100 there is only 1 significant figure. Therefore, your final answer must have only one digit in it: Rounding 100023 = 1, but there is no sensible way that 100023 equals 1. What, then, do you do?
