Solve the Subtraction Equation: 340-340 = ?

$340-340=$

To solve this problem, we'll follow these steps:

• Step 1: Identify that the two numbers involved in the subtraction are both $340$.
• Step 2: Apply the property of subtraction which states that a number minus itself equals zero.

Now, let's work through these steps in detail:
Step 1: The given numbers are $340$ and $340$. Noticing that these are the same number is crucial because it tells us that we will be subtracting a number from itself.

Step 2: Applying the property of subtraction, we calculate:
$340 - 340 = 0$

The subtraction property that a number minus itself equals zero holds true in this case. So, after performing these steps, we find that the solution to the problem is:
