1. Solve Exercise 1 Page 59 Mathematics Grade 3
Problem:
Solution Guide: Calculate the sum of the numbers on the left, compare it with the right side, and then fill in the appropriate symbol in the blank space.
Answer:
2. Solve Exercise 2 Page 59 Mathematics Grade 3
Problem: What expression does each number represent?
Solution Guide: Calculate the values of the expressions on the left column, then combine them with the corresponding values on the right column.
Answer:
We have:
A. 3,000 + 5,000 + 7,000 = 15,000.
B. 61,000 + (4,100 + 4,900) = 70,000.
C. (14,000 + 36,000) + 50,000 = 100,000.
We combine them as follows:

4. Solve Exercise 4 Page 59 Mathematics Grade 3
Problem: A family raises dairy cows. In the first month, they sold 17,250 liters of milk. In the second month, they sold 270 liters more than the first month. How many liters of milk did the family sell in both months?
Solution Guide:
Step 1: Calculate the liters of milk sold in the second month = Liters of milk sold in the first month + 270 liters.
Step 2: Calculate the total liters of milk sold in both months = Liters of milk sold in the first month + Liters of milk sold in the second month.
Answer:
In the second month, they sold:
17,250 + 270 = 17,520 (liters)
In both months, the family sold:
17,250 + 17,520 = 34,770 (liters)
Answer: 34,770 liters of milk.
