Tangohia te 4 i te 8, ka 4.

$$\frac{4\left(3-15\right)-6\left(-8+7\right)^{2}}{7-9}$$

Tangohia te 15 i te 3, ka -12.

$$\frac{4\left(-12\right)-6\left(-8+7\right)^{2}}{7-9}$$

Whakareatia te 4 ki te -12, ka -48.

$$\frac{-48-6\left(-8+7\right)^{2}}{7-9}$$

Tāpirihia te -8 ki te 7, ka -1.

$$\frac{-48-6\left(-1\right)^{2}}{7-9}$$

Tātaihia te -1 mā te pū o 2, kia riro ko 1.

$$\frac{-48-6\times 1}{7-9}$$

Whakareatia te 6 ki te 1, ka 6.

$$\frac{-48-6}{7-9}$$

Tangohia te 6 i te -48, ka -54.

$$\frac{-54}{7-9}$$

Tangohia te 9 i te 7, ka -2.

$$\frac{-54}{-2}$$

Whakawehea te -54 ki te -2, kia riro ko 27.
