Find the Missing Operator: Solving 99?99=1

Choose the correct sign (?):

$99?99=1$

To solve the problem $99?99 = 1$, we need to identify which operation, when applied between the two 99's, results in 1.

Let's evaluate the possible operations:

• Addition: $99 + 99 = 198$. This does not equal 1.
• Subtraction: $99 - 99 = 0$. This does not equal 1.
• Multiplication: $99 \times 99 = 9801$. This does not equal 1.
• Division: $\frac{99}{99} = 1$. This equals 1.

Clearly, the correct operation that results in 1 when applied to 99 and 99 is division. Thus, the correct symbol is the division symbol, represented by a colon $:$.

Therefore, the correct choice for the operation is the division symbol: $99 : 99 = 1$.
