Ngā Upane Otinga

Tangohia te 4 i te 9, ka 5.

$$\frac{5}{5}+\frac{10-2}{4}+\frac{9\times 6}{8}+4$$

Whakawehea te 5 ki te 5, kia riro ko 1.

$$1+\frac{10-2}{4}+\frac{9\times 6}{8}+4$$

Tangohia te 2 i te 10, ka 8.

$$1+\frac{8}{4}+\frac{9\times 6}{8}+4$$

Whakawehea te 8 ki te 4, kia riro ko 2.

$$1+2+\frac{9\times 6}{8}+4$$

Tāpirihia te 1 ki te 2, ka 3.

$$3+\frac{9\times 6}{8}+4$$

Whakareatia te 9 ki te 6, ka 54.

$$3+\frac{54}{8}+4$$

Whakahekea te hautanga \frac{54}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$3+\frac{27}{4}+4$$

Me tahuri te 3 ki te hautau \frac{12}{4}.

$$\frac{12}{4}+\frac{27}{4}+4$$

Tā te mea he rite te tauraro o \frac{12}{4} me \frac{27}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{12+27}{4}+4$$

Tāpirihia te 12 ki te 27, ka 39.

$$\frac{39}{4}+4$$

Me tahuri te 4 ki te hautau \frac{16}{4}.

$$\frac{39}{4}+\frac{16}{4}$$

Tā te mea he rite te tauraro o \frac{39}{4} me \frac{16}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{39+16}{4}$$

Tāpirihia te 39 ki te 16, ka 55.

$$\frac{55}{4}$$

Tauwehe

$$\frac{5 \cdot 11}{2 ^ {2}} = 13\frac{3}{4} = 13.75$$
