It looks like you're trying to perform a mathematical operation involving the variable \( m \) and the number 3. The expression you've written is a bit unclear due to formatting. If I interpret it correctly, you might be trying to evaluate:
\[ m - 3 - 3 \]
This simplifies to:
\[ m - 6 \]
If this interpretation is incorrect, please provide clarification on the expression you'd like to evaluate.
