It looks like you're working with an inequality or equation involving $-1$ and $-m$. Could you clarify if you'd like to solve for $m$ or if you're dealing with a specific type of problem like an inequality, equation, or something else?

Feel free to elaborate!

Here are 5 related questions:

1. Are you trying to solve for $m$ in an equation?
2. Is this part of a larger system of equations or inequalities?
3. Should we be considering absolute values or constraints on $m$?
4. Are there additional terms that need to be included on either side of the expression?
5. Is this problem from a specific mathematical topic (e.g., algebra, calculus)?

Tip: When solving inequalities, remember to reverse the inequality sign if you multiply or divide by a negative number.
