Ngā Upane Otinga

Whakareatia te 0 ki te 25, ka 0.

$$\left(\frac{0}{2-\frac{3}{4}}+18\right)\times 3$$

Me tahuri te 2 ki te hautau \frac{8}{4}.

$$\left(\frac{0}{\frac{8}{4}-\frac{3}{4}}+18\right)\times 3$$

Tā te mea he rite te tauraro o \frac{8}{4} me \frac{3}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\left(\frac{0}{\frac{8-3}{4}}+18\right)\times 3$$

Tangohia te 3 i te 8, ka 5.

$$\left(\frac{0}{\frac{5}{4}}+18\right)\times 3$$

Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$\left(0+18\right)\times 3$$

Tāpirihia te 0 ki te 18, ka 18.

$$18\times 3$$

Whakareatia te 18 ki te 3, ka 54.

$$54$$

Tauwehe

$$2\times 3^{3}$$
