Problem Statement

Юрко мав 8 зошитів у клітинку і 7 у лінійку. Він віддав 5 зошитів у лінійку своєму другові. Скільки зошитів залишилося у Юрка?

Solution 1: Subtraction

To solve this problem using subtraction, we can subtract the number of notebooks given to the friend from the total number of notebooks that Юрко had initially.

Юрко initially had 8 notebooks in the grid and 7 notebooks in the lined format. Therefore, the total number of notebooks he had is 8 + 7 = 15 notebooks.

Юрко gave 5 notebooks to his friend. Subtracting this from the total number of notebooks, we get 15 - 5 = 10 notebooks.

Therefore, Юрко has 10 notebooks left.

Solution 2: Counting

Another way to solve this problem is by counting the number of notebooks that Юрко has left.

Юрко initially had 8 notebooks in the grid and 7 notebooks in the lined format. Therefore, the total number of notebooks he had is 8 + 7 = 15 notebooks.

Юрко gave 5 notebooks to his friend. Subtracting this from the total number of notebooks, we get 15 - 5 = 10 notebooks.

Therefore, Юрко has 10 notebooks left.

Both methods give us the same result: Юрко has 10 notebooks left.
