First of all, if a five-digit number is multiplied by 4 or a five-digit number, then the number represented by "number" can only be less than 3, not 0, because it is a five-digit number, then it can only be 1 or 2, and because any number is multiplied by even number or even number, (test × 4 = number), so "number" =2, and "test" is used as ". So "Kao" = 8. Since the first digit of this number is 2×4=8, it means that the second digit of the number of "Mathematics Mid-term Examination" has no carry after being multiplied by 4, then "Xue" = 1 or 2, and then look at the multiplication formula, test × 4 = 32, and enter 3 for the previous digit, then "Mathematics Mid-term Examination" means that Xue stands for odd number, so Xue =/kloc. Period× 4 advances by 3, (Xue× 4 = 4 and Zhong =7), from which the mantissa of Period =(3+4× Period) can be deduced, and (3+4× Period) advances by 3, and it is concluded that,
