180. Вычисли значения выражений. Исправь ошибки в ответах. 6・4-8・3=48 6・9+26=70 86-(3-6 +20) = 0 9-5+7-6=88 8-8-7-9=0 86-(5-3-2-4) = 69

6 ⋅ 4 - 8 ⋅ 3 = 24 - 24 = 0

6 ⋅ 9 + 26 = 54 + 26 = 80

86 - (3 ⋅ 6 + 20) = 86 - (18 + 20) = 86 - 38 = 48

9 ⋅ 5 + 7 - 6 = 45 + 7 - 6 = 52 - 6 = 46

8 ⋅ 8 - 7 ⋅ 9 = 64 - 63 = 1

86 - (5 ⋅ 3 + 2 ⋅ 4) = 86 - (15 + 8) = 86 - 23 = 63

Ответ: 6・4-8・3=0; 6・9+26=80; 86-(3-6 +20) = 48; 9-5+7-6=46; 8-8-7-9=1; 86-(5-3-2-4) = 63
