Whakareatia te 4 ki te 5, ka 20.

$$7+20-7+4\left(-63\left(\frac{70}{-2}+5\right)-7\right)-93$$

Tāpirihia te 7 ki te 20, ka 27.

$$27-7+4\left(-63\left(\frac{70}{-2}+5\right)-7\right)-93$$

Tangohia te 7 i te 27, ka 20.

$$20+4\left(-63\left(\frac{70}{-2}+5\right)-7\right)-93$$

Whakawehea te 70 ki te -2, kia riro ko -35.

$$20+4\left(-63\left(-35+5\right)-7\right)-93$$
