Ответ: 4

Detailed explanation (для ученика 5 класса по английскому языку):

• Step 1: Understand addition. Adding means putting together two groups.
• Step 2: Start with the first group: 2.
• Step 3: Add the second group which also has 2: 2 + 2.
• Step 4: Count on from 2: 3, then 4.
• Step 5: Conclusion: There are 4 in total. So, 2 + 2 = 4.

If you like, you can visualize it with objects (2 apples + 2 apples = 4 apples) or on a number line (move 2 steps from 0, then 2 more steps to 4).
