Ngā Upane Otinga

Whakareatia te 2 ki te 2, ka 4.

$$|\frac{4+1}{2}-\frac{3}{4}|\times \frac{4}{7}$$

Tāpirihia te 4 ki te 1, ka 5.

$$|\frac{5}{2}-\frac{3}{4}|\times \frac{4}{7}$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{5}{2} me \frac{3}{4} ki te hautau me te tautūnga 4.

$$|\frac{10}{4}-\frac{3}{4}|\times \frac{4}{7}$$

Tā te mea he rite te tauraro o \frac{10}{4} me \frac{3}{4}, me tango rāua mā te tango i ō raua taurunga.

$$|\frac{10-3}{4}|\times \frac{4}{7}$$

Tangohia te 3 i te 10, ka 7.

$$|\frac{7}{4}|\times \frac{4}{7}$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o \frac{7}{4} ko \frac{7}{4}.

$$\frac{7}{4}\times \frac{4}{7}$$

Me whakakore atu te \frac{7}{4} me tōna tau utu \frac{4}{7}.
