4)681-666=15

Answer 2

Sure, let's solve the arithmetic expression step by step:

1. Start with the addition: 999 + 434 = 1433
2. Subtract the next number: 1433 - 829 = 604
3. Add the next number: 604 + 77 = 681
4. Subtract the last number: 681 - 666 = 15

So, the correct result of the expression is 15, not -15 as you mentioned. The correct sequence of operations is:

999 + 434 - 829 + 77 - 666 = 15
