Enter values:
This is optional. For example, if you want to evaluate the expression when x=1, y=2, z=3, enter x,y,z=1,2,3, or simply 1,2,3, if you want the order of variables to be detected automatically.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your input: evaluate $- z + 2 \left(x + 7\right) + \left(y - 1\right)^{2}$ when $x=1$, $y=2$, $z=5$.

Answer: $12\mathtt{\text{}}$.
