Problem Statement

В гараже в одном ряду было 25 машин, а в другом - 32. Уехало 20 машин. Сколько осталось в гараже? Решите задачу 3 способами.

Solution 1: Subtraction

To solve this problem using subtraction, we can subtract the number of cars that left from the total number of cars in the garage.

In the first row, there were 25 cars, and in the second row, there were 32 cars. So, the total number of cars in the garage was 25 + 32 = 57.

If 20 cars left, we can subtract 20 from the total number of cars to find out how many cars are left in the garage.

Solution: Total number of cars in the garage = 57 Number of cars that left = 20

To find the number of cars left in the garage, we subtract the number of cars that left from the total number of cars: 57 - 20 = 37

Therefore, there are 37 cars left in the garage.

Solution 2: Addition and Subtraction

Another way to solve this problem is by using addition and subtraction.

In the first row, there were 25 cars, and in the second row, there were 32 cars. So, the total number of cars in the garage was 25 + 32 = 57.

If 20 cars left, we can subtract 20 from the total number of cars to find out how many cars are left in the garage.

Solution: Total number of cars in the garage = 57 Number of cars that left = 20

To find the number of cars left in the garage, we can add the number of cars in the first and second rows and then subtract the number of cars that left: (25 + 32) - 20 = 57 - 20 = 37

Therefore, there are 37 cars left in the garage.

Solution 3: Counting

The third way to solve this problem is by counting the number of cars left in each row.

In the first row, there were 25 cars, and in the second row, there were 32 cars. If 20 cars left, we can subtract 20 from the number of cars in each row to find out how many cars are left in each row.

Solution: Number of cars in the first row = 25 Number of cars in the second row = 32 Number of cars that left = 20

To find the number of cars left in each row, we subtract the number of cars that left from the number of cars in each row: Number of cars left in the first row = 25 - 20 = 5 Number of cars left in the second row = 32 - 20 = 12

Therefore, there are 5 cars left in the first row and 12 cars left in the second row.
