Решение:
1) 801 - (64 + 168) = 801 - 232 = 569
2) 500 - (291 - 76) = 500 - 215 = 285
3) 400 - 8 * 7 = 400 - 56 = 344
4) 950 + 36 : 9 = 950 + 4 = 954
5) 56 : 7 + 1 = 8 + 1 = 9
6) 6 * 3 : 2 = 18 : 2 = 9
7) 9 * 8 + 154 = 72 + 154 = 226
8) 63 * 7 * 8 = 441 * 8 = 3528
Ответы: 569, 285, 344, 954, 9, 9, 226, 3528
