Solve the Equation: Find the Missing Number in ?-0=100

To solve this problem, we need to understand the properties of zero. Specifically, when zero is subtracted from any number, the original number remains unchanged.

Let's apply this understanding to our problem:

• Step 1: Set up the equation based on the problem statement:

$x - 0 = 100$

• Step 2: Recognize that subtracting zero does not change the value of $x$:

$x = 100$

This shows that the number we were looking for is 100.

Therefore, the solution to the problem is $100$.
