Multiply the horizontal and vertical lines to get the number of intersection points. The multiplication symbol is in the upper left corner. There is an example in the chart, 2 times 4 equals 8, and all the numbers are on the diagonal from the upper left to the lower right.

These lines are 1, 2, 5, 7, 3, 1, 8. 9, 4, 6, 10, the column is 1, 4, 5, 1, 8, 3, 9, 6, 2, 7, 10, and each small square is the product of a row and a column. For example, the answer in the first line is: x, 2, 10, 14, 6, 2, 8, 18, 12,10; And so on.

Law:

1, 2, 4, 7, 1 1, 16, (22), (29),-The difference is: 1, 2, 3, 4, 5, 6, …

2,5, 10,17,26, (37), (50)-the difference is: 3,5,7,9, …

0, 3, 8, 15, 24, (35), (48)-the difference is: 3, 5, 7, 9, …

Find a pattern to fill in the blanks: 9- 1 = 8, 16-4 = 12, 25-9 = 16, 36- 16 = 20, 49-25 = 24.
