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.
