Answer:

3. Solve exercise 3 on page 39 of Grade 4 Math Textbook

Problem:
A district planted 325,164 trees for timber and 60,830 fruit trees. How many trees did the district plant in total?

Solution method:
- The problem states:
+ Timber trees: 325164 (trees)
+ Fruit trees: 60830 (trees)
- The problem asks: How many trees did the district plant in total.
* Solution method: The total number of trees planted by the district = Number of timber trees + Number of fruit trees.
- Setting up: Refer back to the setup instructions in the section Solve exercise 1 on page 39 of Grade 4 Math Textbook.

- Set up the calculation and then perform the operation. When setting up the calculation, make sure that the numbers in the same row are aligned.
- Perform addition from right to left.
4682 + 2305 =
+ 2 plus 5 equals 7, write 7.
+ 8 plus 0 equals 8, write 8.
+ 6 plus 3 equals 9, write 9.
+ 4 plus 2 equals 6, write 6.
So: 4682 + 2305 = 6987.
Repeat the same process for the remaining questions.

- Set up the calculation and then perform the operation. When setting up the calculation, make sure that the numbers in the same row are aligned.
- Perform addition from right to left.
4685 + 2347 =
+ 5 plus 7 equals 12, write 2 carry 1.
+ 8 plus 4 equals 12, add 1 to get 13, write 3 carry 1
+ 6 plus 3 equals 9, add 1 to get 10, write 0 carry 1
+ 4 plus 2 equals 6, add 1 to get 7, write 7.
So: 4685 + 2347 = 7032.
Repeat the same process for the remaining questions.

* Step-by-step guide to solve problem 3 on page 39 of Math 4 textbook
The problem requires finding the 'total' number of trees (wood + fruit) in a district. Hence, pay attention to whether we know the quantities of each type yet. Then, by finding the sum of the two types, we will determine the answer to the problem.

* Step-by-step guide to solve problem 4 on page 39 of Math 4 textbook
This is a type of problem involving finding the unknown in a calculation, so we apply the rules:
- To find the number being subtracted, we take the difference added to the number being subtracted.
- To find this term, we take the sum minus the other term.

A comprehensive explanation of the content in the Math 4 problem-solving section on page 68 has been provided for students to refer to and prepare for better mastery of Math 4.

In addition to the learned content, students can prepare and explore the content in the Math 4 problem-solving section on page 57 to grasp the knowledge in the Math 4 curriculum better.

The Math 4 problem-solving section on pages 33, 34 of the textbook - Exercises, Charts has been carefully guided. In the fourth-grade math problem-solving document, the topic of addition problems will help students understand more clearly how to perform addition and know how to set up the calculation properly and perform the addition according to which rule. Typically, for addition operations, we add sequentially from right to left, and students can completely perform as well as refer to detailed examples and exercise-solving instructions in the document. If students encounter addition calculations requiring memorization, they need to add the smaller rows first, and any excess will continue to be remembered and added to the immediately adjacent row to produce the most accurate result.

In the next task, we will continue to explore problems 1, 2, 3, 4 on page 40 of the Math 4 textbook - Subtraction, inviting students to follow along for more details.

Above is the solution to exercises on page 39 of the Math 4 textbook in the section of fourth-grade math exercise solutions. Students can review the exercise solutions on pages 36, 37 of the Math 4 textbook that have been solved earlier or preview the exercise solutions on pages 40, 41 of the Math 4 textbook to improve their understanding of fourth-grade math.
