Find each product or quotient where possible. See Example 2. 0/(-8)

검증된 단계별 안내
1
First, identify the operation involved in the expression. Here, the expression is "0 — -8", which means 0 minus (-8).
Recall that subtracting a negative number is equivalent to adding its positive counterpart. So, rewrite the expression as \(0 - (-8) = 0 + 8\).
Next, perform the addition: \(0 + 8\).
Since adding zero to any number leaves it unchanged, the result simplifies to 8.
Therefore, the expression simplifies to 8.
