Different Chinese characters in the following questions in primary school mathematics represent different numbers, and the same person represents the same number. What number does each Chinese character represent? ... The formula is: (below) Look at the whole formula first. When XXXXX is multiplied by 4 or 5 digits, it can be calculated that the dispute is 1 or 2 (because 4x < 10).

Try to be an eagle and then put forward one hypothesis after another.

× 4 We assume that the contention is 1, so any number multiplied by 4 cannot be equal to an odd number, so the contention can only be 2.

How many times is 4=2 (or 12, 22, 32, 42)? There are only three and eight numbers.

Suppose the eagle is 2 (see ten thousand places), then 2×4=8≠2, then the eagle is 8.

Look at thousands more. When ×4= young, we can synthesize 10,000 digits. When we find that ×4 can't be carried, it can only be 0, 1 (the digits can't be the same, so there is no 2). Look at it, 8 (Eagle) ×4=32, and enter three. If it is 0, young× 4+3 equals several tens (multiples of 10), 10-3=7, young× 4 equals several seventeen (odd numbers), but it is not true, so it is 65438.

After the unit enters three, chicks× 4 = dozens 1. If you don't score three, the chicken × 4 equals dozens 18, then the chicken is 2 or 7. Suppose the chicken is 2, and the chicken × 4 will not carry. X×4= a number with X, there is none, so young is 7.

Look at thousands, 4×2 (contention) =8 (eagle), and thousands do not carry. 1 (when) ×4=4, and the young one is 7, so one percent should enter 3. 4×X= 30, X=8 or 9, and the numbers cannot be repeated, so the decimal number is 9.

Answer: for =2, when = 1, small =9, young =7, eagle =8.
