2 + 2

Поскольку предмет указан как английский язык, объяснение будет на английском и понятным языком для средней школы.

Step-by-step explanation

• Idea: 2 + 2 is the operation of adding two groups of two objects.
• Visualize: imagine two apples in one group and two apples in another group.
  • Count all the apples: 1, 2, 3, 4.
• Equation form: 2 + 2 = 4.
• In words: “Two plus two equals four.” Another common phrasing: “Two and two make four.”
• Number line method (quick check): start at 2 on the number line, move 2 steps to the right, you land on 4.
• Quick mental check: you can think of it as doubling 2 (2 × 2 = 4) in this simple case.

Answer

• 2 + 2 = 4

If you’d like, I can also give a short bilingual version or a few practice variations (e.g., 3 + 2, 5 + 0) to reinforce the concept in English.
