РЕШИ КАЖДЫЙ ПРИМЕР И ЗАПИШИ ПО ОБРАЗЦУ. 1. УМНОЖЕНИЕ ДВУЗНАЧНОГО ЧИСЛА НА ОДНОЗНАЧНОЕ 16.6= Рассуждаем так: 16 представляем в виде суммы разрядных слагаемых 10 и 6. Сначала 10 умножаем на 6, затем 6 умножаем на 6. Полученные числа складываем. ОБРАЗЕЦ ЗАПИСИ: 166(10+6)6106+66=60+36=96

1) 16 ⋅ 7 = (10 + 6) ⋅ 7 = 10 ⋅ 7 + 6 ⋅ 7 = 70 + 42 = 112 2) 19 ⋅ 6 = (10 + 9) ⋅ 6 = 10 ⋅ 6 + 9 ⋅ 6 = 60 + 54 = 114 3) 14 ⋅ 8 = (10 + 4) ⋅ 8 = 10 ⋅ 8 + 4 ⋅ 8 = 80 + 32 = 112 4) 19 ⋅ 5 = (10 + 9) ⋅ 5 = 10 ⋅ 5 + 9 ⋅ 5 = 50 + 45 = 95 5) 26 ⋅ 2 = (20 + 6) ⋅ 2 = 20 ⋅ 2 + 6 ⋅ 2 = 40 + 12 = 52 6) 37 ⋅ 3 = (30 + 7) ⋅ 3 = 30 ⋅ 3 + 7 ⋅ 3 = 90 + 21 = 111 7) 12 ⋅ 9 = (10 + 2) ⋅ 9 = 10 ⋅ 9 + 2 ⋅ 9 = 90 + 18 = 108 8) 13 ⋅ 5 = (10 + 3) ⋅ 5 = 10 ⋅ 5 + 3 ⋅ 5 = 50 + 15 = 65 9) 15 ⋅ 8 = (10 + 5) ⋅ 8 = 10 ⋅ 8 + 5 ⋅ 8 = 80 + 40 = 120 10) 23 ⋅ 4 = (20 + 3) ⋅ 4 = 20 ⋅ 4 + 3 ⋅ 4 = 80 + 12 = 92

Ответ: 1) 112; 2) 114; 3) 112; 4) 95; 5) 52; 6) 111; 7) 108; 8) 65; 9) 120; 10) 92
