Fill in 6 digits 1-6 at the bottom, and the total is equal to 10.
We have six numbers, 1-6. We need to fill them in the figure below, so that the sum of the three numbers in each row is equal to 10.

Suppose the six positions in the following figure are A, B, C, D, E and F, where A, B and C are the first row and D, E and F are the second row. According to the topic, the following equations can be established: the sum of the first line is a+b+c= 10, and the sum of the second line is d+e+f= 10. At the same time, these six numbers cannot be repeated, that is, A ≠ B ≠ C ≠ D E.

Therefore, all possible filling methods are as follows:

The first line: 1, 4, 5; The second line: 2, 3, 6.

The first line: 1, 6, 3; The second line: 2, 5, 4.

The first line: 2, 4, 6; Second line: 1, 3, 5.

Common mathematical number games:

1, blackjack game: given four numbers, add, subtract, multiply and divide, the result is equal to 24.

2. Sudoku game: in a 9x9 grid, fill in the number 1-9, so that the numbers are not repeated in each row, column and 3x3 small grid.
