Tangohia te 66 i te 82, ka 16.

$$66+\frac{16}{8}\left(\frac{30+1}{2}-22\right)$$

Whakawehea te 16 ki te 8, kia riro ko 2.

$$66+2\left(\frac{30+1}{2}-22\right)$$

Tāpirihia te 30 ki te 1, ka 31.

$$66+2\left(\frac{31}{2}-22\right)$$

Me tahuri te 22 ki te hautau \frac{44}{2}.

$$66+2\left(\frac{31}{2}-\frac{44}{2}\right)$$

Tā te mea he rite te tauraro o \frac{31}{2} me \frac{44}{2}, me tango rāua mā te tango i ō raua taurunga.

$$66+2\times \frac{31-44}{2}$$

Tangohia te 44 i te 31, ka -13.

$$66+2\left(-\frac{13}{2}\right)$$

Me whakakore te 2 me te 2.

$$66-13$$

Tangohia te 13 i te 66, ka 53.
