This is an Olympic math problem. I'll call it soon
This is an overlapping problem. You should know the answer on the evening of June 15. Four circles intersect each other. They divide the four circles into 13 regions. If you add 1 ~ 13 to these regions respectively, then add the numbers in the four circles, and finally add the sum of the four circles, how small is the minimum sum?
Of the 13 regions, one is calculated four times, three times, two times, and four at a time,
Put the smallest one where we calculate four times;
Put 2,3,4,5 in the place where we calculate three times;
Put 6, 7, 8 and 9 where they are calculated twice;
Put 10, 11, 12 and 13 in the place where they are calculated once;
The total is 152
A six digit n satisfies the following conditions: 1. N is a complete square. 2. The last three numbers of N are more than the first three numbers. Find n and write your solution (n may be 123124, although it is not a complete square)
I won't be able to solve the first problem of British Olympic mathematics
Suppose the first three digits of six digit n are x, then the last three digits are x + 1, so n = 1000x + X + 1 = 1001x + 1
Because n is a perfect square, suppose n = m ^ 2, because 10 ^ 5
