1. The problem asks why $8 - 2$ equals $+6$ in the final answer. 2. Start with the subtraction: $8 - 2$ means you take away 2 from 8. 3. Calculate the difference: $8 - 2 = 6$. 4. The result is positive because 8 is greater than 2, so subtracting 2 leaves a positive number. 5. Writing $+6$ just emphasizes that the result is positive, but $6$ and $+6$ represent the same number. 6. Therefore, $8 - 2 = +6$ means the answer is positive six, which is simply $6$.
