Find the value of the expressions for the given values of the variable(s).

- \(\dfrac{x+(-7)}{-1}\), when \(x=-3\)
- \((3-(-4)q)^2\), when \(q=3\)
- \(-5s+(-6)v-3\), when \(s=2\) and \(v=7\)
- \(m(-7-z)\), when \(m=-5\) and \(z=-2\)

- How did you know in which order to perform the operations?
- What are the possible mistakes that one might make when performing the operations?
