Aromātai

$$-\frac{164}{21}\approx -7.80952381$$

Ngā Upane Otinga

Whakareatia te 9 ki te 7, ka 63.

$$-\frac{63+8}{7}+\frac{\frac{2\times 3+1}{3}}{1}$$

Tāpirihia te 63 ki te 8, ka 71.

$$-\frac{71}{7}+\frac{\frac{2\times 3+1}{3}}{1}$$

Whakareatia te 2 ki te 3, ka 6.

$$-\frac{71}{7}+\frac{\frac{6+1}{3}}{1}$$

Tāpirihia te 6 ki te 1, ka 7.

$$-\frac{71}{7}+\frac{\frac{7}{3}}{1}$$

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$-\frac{71}{7}+\frac{7}{3}$$

Ko te maha noa iti rawa atu o 7 me 3 ko 21. Me tahuri -\frac{71}{7} me \frac{7}{3} ki te hautau me te tautūnga 21.

$$-\frac{213}{21}+\frac{49}{21}$$

Tā te mea he rite te tauraro o -\frac{213}{21} me \frac{49}{21}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-213+49}{21}$$

Tāpirihia te -213 ki te 49, ka -164.

$$-\frac{164}{21}$$

Tauwehe

$$-\frac{164}{21} = -7\frac{17}{21} = -7.809523809523809$$
