Problem Statement

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

Solution 1: Subtraction

One way to solve this problem is by using subtraction. We can subtract the number of cars that left from the total number of cars in the garage to find the remaining cars.

1. The total number of cars in the garage is the sum of the cars in the two rows: 25 + 32 = 57. 2. Subtract the number of cars that left, which is 20: 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. We can add the number of cars in the two rows and then subtract the number of cars that left.

1. The number of cars in the first row is 25. 2. The number of cars in the second row is 32. 3. Add the number of cars in the two rows: 25 + 32 = 57. 4. Subtract the number of cars that left, which is 20: 57 - 20 = 37.

Therefore, there are 37 cars left in the garage.

Solution 3: Counting

A third way to solve this problem is by counting the remaining cars after some cars have left.

1. Start with the total number of cars in the garage, which is 25 + 32 = 57. 2. Subtract the number of cars that left one by one: 57 - 1 = 56, 56 - 1 = 55, and so on, until we subtract 20 cars. 3. After subtracting 20 cars, we are left with 57 - 20 = 37 cars.

Therefore, there are 37 cars left in the garage.

In conclusion, there are 37 cars left in the garage, regardless of the method used to solve the problem.
