Answer 1

1) (68 : 4+ 13): 6+ ((85 - 28) : 3 + 72: (6-3) - 11)- 18 - 189; 8) - 122.

```

= (17 + 13): 6 + ((57) : 3 + 72: 3) - 18 - 189; 8) - 122

= 30: 6 + (19 + 72) - 18 - 189; 8) - 122

= 5 + 91 - 18 - 189; 8) - 122

= 96 - 18 - 189; 8) - 122

= 78 - 189; 8) - 122

= -111; 8) - 122

= -111 - 122

= -233

```

Ответ: 1) -233

2) 85 : 17 (21- 45 (54: 6)) +90 : 15 (56: 3)

```

= 85 : 17 (21- 45 * 9) +90 : 15 (56: 3)

= 85 : 17 (-378) +90 : 15 (18)

= 85 : -6462 +90 : 270

= -0,013 + 3.333

= 3.32

```

Ответ:3.32
