There are many different ways to understand the riddle. The following is an explanation for your reference: one way is that the climax refers to "high" and "tide", that is, two and seven, and the homonym of "overlapping" is 784, so it is 2774; Another understanding is that when two identical numbers are connected, it means double growth and unbridled, so the last four numbers are 88033.

1, the basic concept of iteration times

Iteration times, mathematical terms. When the number on each digit is the same, it can be called "overlapping number". Mathematical "overlap number" and "overlap number" are different. "Overlapping number" is the number at a specific position in the number array; "Overlapping number" is a number with the same number on it.

2. Basic characteristics

Every number is the same. Two-digit overlap is a multiple of 1 1, and three-digit overlap is a multiple of11. ...

3. Reference example

Clever calculation method of multiplying the number of iterations by the complement: Example1:66 ╳ 28 "66" refers to the number of iterations and "28" refers to the complement. Add 1 to the complement, and then multiply the number of iterations by 2+1= 3,3 ╳ 6 =18. 8╳6=48, then the product of 66╳28 is 18 plus 48. 66╳28= 1848。

Example 2: 66 ╳ 82 "66" means overlapping number and "82" means complement. Add 1 to the first number of the complement and multiply it by the first number 8+1= 9,9 ╳ 6 = 54, then the product of 66╳82 is the product of "54" plus two mantissas 2 ╳ 6.

Example 3: 66╳82=54 12, 44 ╳ 82 "44" is the overlapping number and "82" is the complement. Add 1 to the first number of the complement and multiply it by the first number 8+1= 9,9 ╳ 4 = 36, then the product of 44╳82 is the product of 36 plus two mantissas "4" and "2". 4╳2=8, then the product of 44╳836 is 18 plus 8. 44╳82=3608
