Solve the Subtraction Equation: 100-100 = ?

To solve this problem, we need to subtract 100 from 100 using basic arithmetic.

• Step 1: Identify the operation as subtraction, $100 - 100$.
• Step 2: Apply the arithmetic property: Subtract any number from itself, and the result is $0$.
• Step 3: Calculate: $100 - 100 = 0$.

Subtracting the number from itself means we are finding the difference between two equal numbers, which is always zero.

Therefore, the result of subtracting 100 from 100 is $\mathbf{0}$.
