Answer 1

1)=1641
2)=372814884
3)=-27,756
4)=0,185

Answer 2

1) (+298 - (-377) + (-122)) - (-526 - 318) =

First, we simplify the expression inside the parentheses: 298 - (-377) = 298 + 377 = 675 675 + (-122) = 553

Next, we simplify the expression inside the second set of parentheses: -526 - 318 = -844

Now, we can substitute the simplified values back into the original expression: 553 - (-844) = 553 + 844 = 1397

Therefore, the answer is 1397.

2) (-2 + 378 + (-1 + 299)) + (3 + 728 + 5 + 799 + (-638)) =

First, we simplify the expression inside the parentheses: -2 + 378 = 376 -1 + 299 = 298

Next, we simplify the expression inside the second set of parentheses: 3 + 728 + 5 + 799 + (-638) = 1097

Now, we can substitute the simplified values back into the original expression: 376 + 298 + 1097 = 1771

Therefore, the answer is 1771.

3) (-17.38 + (-25.045)) + (18.79 + (-7.08) + (-11.201)) =

First, we simplify the expression inside the parentheses: -17.38 + (-25.045) = -42.425 18.79 + (-7.08) + (-11.201) = 0.509

Now, we can substitute the simplified values back into the original expression: -42.425 + 0.509 = -41.916

Therefore, the answer is -41.916.

4) (0.275 + (-1.038) - 2.1) - (-3.96) + (1.011 + 2.123 + 0.2) =

First, we simplify the expression inside the parentheses: 0.275 + (-1.038) = -0.763 -0.763 - 2.1 = -2.863

Next, we simplify the expression inside the second set of parentheses: 1.011 + 2.123 + 0.2 = 3.334

Now, we can substitute the simplified values back into the original expression: -2.
