Whakawehea te 40 ki te 5, kia riro ko 8.

$$8\times 5+\frac{6}{2}\times 3+4-\frac{5\times 2}{10}$$

Whakareatia te 8 ki te 5, ka 40.

$$40+\frac{6}{2}\times 3+4-\frac{5\times 2}{10}$$

Whakawehea te 6 ki te 2, kia riro ko 3.

$$40+3\times 3+4-\frac{5\times 2}{10}$$

Whakareatia te 3 ki te 3, ka 9.

$$40+9+4-\frac{5\times 2}{10}$$

Tāpirihia te 40 ki te 9, ka 49.

$$49+4-\frac{5\times 2}{10}$$

Tāpirihia te 49 ki te 4, ka 53.

$$53-\frac{5\times 2}{10}$$

Whakareatia te 5 ki te 2, ka 10.

$$53-\frac{10}{10}$$

Whakawehea te 10 ki te 10, kia riro ko 1.

$$53-1$$

Tangohia te 1 i te 53, ka 52.

$$52$$
