СЛОЖЕНИЕ И ВЫЧИТАНИЕ ТИПА 40 + 16, 40 – 16
40 + 16 = ? Число 16 раскладываю на сумму разрядных слагаемых 10 и 6.
Десятки складываю с десятками: 40 + 10 = 50. Потом к 50 прибавляю 6. Получается число 56. 40 + 16 = 40 + (10 + 6) = (40 + 10) + 6 = 50 + 6 = 56.
40 – 16 = ? Число 16 раскладываю на сумму разрядных слагаемых 10 и 6.
Десятки вычитаю из десятков: 40 – 10 = 30. Потом из 30 вычитаю 6. Получается
число 24. 40 – 16 = 40 – (10 + 6) = (40 – 10) – 6 = 30 – 6 = 24.
