Chapter 1, Problem 56

Find each product or quotient where possible. 0(-8)

Verified step by step guidance
1
Identify the operation involved in the expression. Here, the expression is a product: \(0 \times (-8)\).
Recall the multiplication property of zero: any number multiplied by zero equals zero.
Apply this property to the expression: multiply 0 by -8.
Since multiplying zero by any number results in zero, the product is zero.
Therefore, the expression \(0 \times (-8)\) simplifies directly to 0.
