This is a math problem in grade one, and we should do it in the way we learned in grade one. The child hasn't learned multiplication and division in the first grade, so the idea of solving the problem is as follows:

(1) Calculate how many sticks are there in the second line than in the first line:

10-4 = 6 (root)

② Divide the extra stick into two parts:

six

/ \

1 5

2 4

3 3

As you can see, the extra sticks are divided into two parts on average, with three in each part, so:

Answer: After the second line gives three sticks to the first line, there are as many sticks in the two lines.
