Me tahuri te 8 ki te hautau \frac{120}{15}.

$$\frac{120}{15}-\frac{8}{15}+\frac{2\times 3+2}{3}o\times \frac{5\times 4+1}{4}\times 28-13$$

Tā te mea he rite te tauraro o \frac{120}{15} me \frac{8}{15}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{120-8}{15}+\frac{2\times 3+2}{3}o\times \frac{5\times 4+1}{4}\times 28-13$$

Tangohia te 8 i te 120, ka 112.

Tāpirihia te 20 ki te 1, ka 21.

$$\frac{112}{15}+\frac{8}{3}o\times \frac{21}{4}\times 28-13$$

Me whakarea te \frac{8}{3} ki te \frac{21}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{112}{15}+\frac{8\times 21}{3\times 4}o\times 28-13$$

Mahia ngā whakarea i roto i te hautanga \frac{8\times 21}{3\times 4}.

$$\frac{112}{15}+\frac{168}{12}o\times 28-13$$

Whakawehea te 168 ki te 12, kia riro ko 14.

$$\frac{112}{15}+14o\times 28-13$$

Whakareatia te 14 ki te 28, ka 392.

$$\frac{112}{15}+392o-13$$

Me tahuri te 13 ki te hautau \frac{195}{15}.

$$\frac{112}{15}+392o-\frac{195}{15}$$

Tā te mea he rite te tauraro o \frac{112}{15} me \frac{195}{15}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{112-195}{15}+392o$$

Tangohia te 195 i te 112, ka -83.
