Evaluate Addition Operation: Start by evaluating the expression from left to right, taking into account the order of operations. The first operation is an addition: 6+2. 6+2=8
Subtract Negative Number: Next, we have the subtraction of a negative number, which is the same as adding its positive counterpart: 8−(−1). 8−(−1)=8+1=9
Add Negative Term: Finally, we add the last term, which is negative: 9+(−8). 9+(−8)=9−8=1
