Question

1)50 – 110 +70 – (-10) – 30; 2)-34 – 46 + 34 +46 + 85 – 115.

Answer 1

Ответ:

50-110+70—(-10)-30=-10

-34-46+34+46+85-115=-30

Answer 2

Sure, I can help you with those calculations:

1. 50 - 110 + 70 - (-10) - 30 = 50 - 110 + 70 + 10 - 30 = (50 + 70 + 10) - (110 + 30) = 130 - 140 = -10

2. -34 - 46 + 34 + 46 + 85 - 115 = (-34 + 34 + 46 + 46 + 85) - 115 = 181 - 115 = 66

So, the results are:

1. -10
2. 66
