Solve the Equation: Zero Times Unknown Equals Zero

$0\times?=0$

To solve this problem, let's focus on the principle of multiplication concerning zero:

• Step 1: Understand that any number multiplied by zero equals zero.
• Step 2: Apply this understanding to the given equation $0 \times ? = 0$.
• Step 3: Recognize that since zero multiplied by any number results in zero, the missing value can be any real number.

Now, let's work through these steps:

Step 1: The multiplication property of zero states that when a number is multiplied by zero, the product is always zero.

Step 2: In the equation $0 \times ? = 0$, we need to determine what value of the question mark satisfies this condition. Based on the multiplication property of zero, we know that this condition holds for any real number.

Step 3: Therefore, regardless of what number we replace the question mark with, as long as it’s a real number, the equation will be true since $0 \times \text{any number} = 0$.

Therefore, the solution to this problem is that all values satisfy the equation. This conclusion matches the choice "All answers are correct."

Therefore, the correct answer is All answers are correct.
