Tāpirihia te 13 ki te 7, ka 20.

$$2\times 20+2\times \frac{1}{2}\times 2\times \frac{22}{7}\times \frac{35}{10}$$

Whakareatia te 2 ki te 20, ka 40.

$$40+2\times \frac{1}{2}\times 2\times \frac{22}{7}\times \frac{35}{10}$$

Me whakakore te 2 me te 2.

$$40+2\times \frac{22}{7}\times \frac{35}{10}$$

Tuhia te 2\times \frac{22}{7} hei hautanga kotahi.

$$40+\frac{2\times 22}{7}\times \frac{35}{10}$$

Whakareatia te 2 ki te 22, ka 44.

$$40+\frac{44}{7}\times \frac{35}{10}$$

Whakahekea te hautanga \frac{35}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$40+\frac{44}{7}\times \frac{7}{2}$$

Me whakarea te \frac{44}{7} ki te \frac{7}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$40+\frac{44\times 7}{7\times 2}$$

Me whakakore tahi te 7 i te taurunga me te tauraro.

$$40+\frac{44}{2}$$

Whakawehea te 44 ki te 2, kia riro ko 22.

$$40+22$$

Tāpirihia te 40 ki te 22, ka 62.
