subtract w from v, add the result to u, then triple what you have

subtract w from v, add the result to u, then triple what you have

Take this algebraic expression in parts:

1. Subtract w from v: v - w
2. Add the result to u (the result is #1): u + v - w
3. Triple what you have. This means multiply the result in #2 by 3:

3(u + v - w)
