Tangohia te 1 i te 3, ka 2.

$$2\times 2+3\left(1-2\times 2\right)+2\left(4-1\right)\left(2+1\right)$$

Whakareatia te 2 ki te 2, ka 4.

$$4+3\left(1-2\times 2\right)+2\left(4-1\right)\left(2+1\right)$$

Whakareatia te 2 ki te 2, ka 4.

$$4+3\left(1-4\right)+2\left(4-1\right)\left(2+1\right)$$

Tangohia te 4 i te 1, ka -3.

$$4+3\left(-3\right)+2\left(4-1\right)\left(2+1\right)$$

Whakareatia te 3 ki te -3, ka -9.
