Find the Missing Mathematical Sign in 360?360=0

To solve this problem, we'll determine which arithmetic operation, when applied to two numbers (360), results in zero. Here, we consider the basic arithmetic operations: addition, subtraction, multiplication, and division.

• Addition: $360 + 360 = 720$, which is not zero.
• Subtraction: $360 - 360 = 0$. This operation results in zero, satisfying the condition.
• Multiplication: $360 \times 360 = 129600$, not zero.
• Division: $360 \div 360 = 1$, again not zero.

Thus, subtraction between two identical numbers results directly in zero. This confirms that the correct operation is subtraction.

Therefore, the correct sign is $-$.
