1. Вычисли 1. 36 + 24 = 60 2. 58 − 17 = 41 3. 47 + 8 = 55 4. 90 − 45 = 45 5. 64 + 9 = 73 6. 70 − 26 = 44
2. Найди значение выражений 1. 25 + 15 − 10 = 2. 60 − 20 + 8 = 3. 40 − (8 + 12) =
2. Найди значение выражений 1. 25 + 15 − 10 = 30 2. 60 − 20 + 8 = 48 3. 40 − (8 + 12) = 20
3. Реши уравнения 1. x + 27 = 65 2. 54 − x = 18 3. x + 19 = 40
3. Реши уравнения 1. x + 27 = 65 → x = 38 2. 54 − x = 18 → x = 36 3. x + 19 = 40 → x = 21
