If a number is multiplied by 0, what is the result?

• A. 0
• B. 1
• C. The number itself
• D. Undefined

Answer: (A)

When a number is multiplied by 0, the result is always 0. This property is a fundamental aspect of multiplication in arithmetic. The reasoning behind this is that multiplication can be thought of as repeated addition. For example, if you have a number, say 5, and you multiply it by 0, you are essentially saying you have 0 groups of 5, which results in 0. This principle applies to any number, regardless of whether it is positive, negative, or even a fraction. Thus, multiplying any number by 0 will yield zero as the final result. This consistent outcome is a defining characteristic of the number 0 in multiplication, reinforcing the notion that zero represents the absence of quantity.
