Find the Missing Operator: Solving 7?7=0

Let's evaluate each option:

• Addition: $7 + 7 = 14$
• Subtraction: $7 - 7 = 0$
• Multiplication: $7 \times 7 = 49$
• Division: $7 \div 7 = 1$

Given we want the result to be 0, the operation that satisfies this condition is subtraction.

Therefore, the correct operation between the two 7s to equal 0 is $-$.
