Whakawehea te 9 ki te 3, kia riro ko 3.

$$\frac{3+7\times 4}{17+4+12-2}+\frac{25\times 4}{10}$$

Whakareatia te 7 ki te 4, ka 28.

$$\frac{3+28}{17+4+12-2}+\frac{25\times 4}{10}$$

Tāpirihia te 3 ki te 28, ka 31.

$$\frac{31}{17+4+12-2}+\frac{25\times 4}{10}$$

Tāpirihia te 17 ki te 4, ka 21.

$$\frac{31}{21+12-2}+\frac{25\times 4}{10}$$

Tāpirihia te 21 ki te 12, ka 33.

$$\frac{31}{33-2}+\frac{25\times 4}{10}$$

Tangohia te 2 i te 33, ka 31.

$$\frac{31}{31}+\frac{25\times 4}{10}$$

Whakawehea te 31 ki te 31, kia riro ko 1.

$$1+\frac{25\times 4}{10}$$

Whakareatia te 25 ki te 4, ka 100.

$$1+\frac{100}{10}$$

Whakawehea te 100 ki te 10, kia riro ko 10.
