Final answer:
The calculation of the arithmetic expression 10 + 10 - 5 + 10 + 5 - 50 + 100 equals 80, after adding all positive numbers and subtracting the sums of the negatives.
Step-by-step explanation:
The problem provided is a basic arithmetic operation involving addition and subtraction: 10 + 10 - 5 + 10 + 5 - 50 + 100. To solve this, we can simply combine the like terms following the proper order of operations, which in this case, is doing addition and subtraction from left to right as they have the same precedence.
- First add the positive numbers together: 10 + 10 + 10 + 100 = 130.
- Then, add the negative numbers: -5 + 5 - 50 = -50 (since -5 + 5 cancels each other out).
- Finally, combine the sums of the positive and negative numbers: 130 - 50 = 80.
So, the result of 10 + 10 - 5 + 10 + 5 - 50 + 100 is 80.
