Practice Exercises
1. Solve Exercise 1 on Page 61 of Mathematics Grade 3 Textbook
Problem: Mental Calculation.
Solution:
+ Perform addition and subtraction operations from left to right.
+ For expressions containing parentheses, evaluate the operations within the parentheses first.
Answers:
a) 73,000 - 3,000 + 10,000 = 70,000 + 10,000
= 80,000
b) 25,000 - (4,000 + 1,000) = 25,000 - 5,000
= 20,000
c) 47,000 + (5,000 - 2,000) = 47,000 + 3,000
= 50,000
2. Solve Exercise 2 Page 61 Math Textbook Grade 3
The problem statement: What is the number?

Solving Exercise 3 on Page 61 of the 3rd Grade Math Textbook
Problem: A person travels from Cà Mau Province to the capital city Hanoi by road, passing through Ho Chi Minh City.
Solution: Distance from Ho Chi Minh City to Hanoi = Distance from Cà Mau to Hanoi - Distance from Cà Mau to Ho Chi Minh City.
Answer: The distance from Ho Chi Minh City to Hanoi in kilometers is: 2,034 - 308 = 1,726 km.
Challenge: Solve the following arithmetic problems mentally and write down the appropriate symbols for each operation.
Solution: a) 50,000 - 20,000 = 30,000 b) 50,000 + 30,000 = 80,000 c) 400 x 5 = 2,000 d) (2,000 + 6,000) ÷ 4 = 2,000.
