$$30\cdot \left(1\right)\cdot 22\cdot \left(4^2\right)-3\cdot {\left(1-2\right)}^2$$

$$30\cdot 1\cdot 22\cdot \left(4^2\right)-3\cdot {\left(1-2\right)}^2$$

$$30\cdot 1\cdot 22\cdot \left(4^2\right)-3\cdot {\left(1-2\right)}^2$$

$$30\cdot 1\cdot 22\cdot \left(16\right)-3\cdot {\left(1-2\right)}^2$$

$$30\cdot 1\cdot 22\cdot 16-3\cdot {\left(1-2\right)}^2$$

$$30\cdot 1\cdot 22\cdot 16-3\cdot {\left(-1\right)}^2$$

$$30\cdot 1\cdot 22\cdot 16-3\cdot -1^2$$

$$30\cdot 1\cdot 22\cdot 16-3\cdot 1$$

$$30\cdot 1\cdot 22\cdot 16-3\cdot 1$$

$$30\cdot 22\cdot 16-3\cdot 1$$

$$660\cdot 16-3\cdot 1$$

$$10560-3\cdot 1$$

$$10560-3$$

$$10560-3$$

$$10557$$
