Answer 1

Problem Statement

В коробке было 12 карандашей. Лена взяла из коробки сначала 3, а потом еще 2. Сколько осталось в коробке? Решить задачу двумя способами.

Solution 1: Subtraction

To solve this problem using subtraction, we can start with the total number of pencils in the box (12) and subtract the number of pencils that Lena took out (3 + 2).

1. Start with the total number of pencils in the box: 12. 2. Subtract the number of pencils Lena took out: 12 - 3 - 2 = 7.

Therefore, there are 7 pencils left in the box.

Solution 2: Counting

Another way to solve this problem is by counting the remaining pencils in the box after Lena took some out.

1. Start with the total number of pencils in the box: 12. 2. Lena took out 3 pencils, so subtract 3 from the total: 12 - 3 = 9. 3. Lena then took out 2 more pencils, so subtract 2 from the remaining total: 9 - 2 = 7.

Therefore, there are 7 pencils left in the box.

Both methods give us the same result: there are 7 pencils left in the box.
