Whakaoti i te -1/10--61/2=

$$\frac { - 1 } { 10 } - - 6 \frac { 1 } { 2 } =$$

Aromātai

$$\frac{32}{5}=6.4$$

Ngā Upane Otinga

Ka taea te hautanga \frac{-1}{10} te tuhi anō ko -\frac{1}{10} mā te tango i te tohu tōraro.

$$-\frac{1}{10}-\left(-\frac{6\times 2+1}{2}\right)$$

Whakareatia te 6 ki te 2, ka 12.

$$-\frac{1}{10}-\left(-\frac{12+1}{2}\right)$$

Tāpirihia te 12 ki te 1, ka 13.

$$-\frac{1}{10}-\left(-\frac{13}{2}\right)$$

Ko te tauaro o -\frac{13}{2} ko \frac{13}{2}.

$$-\frac{1}{10}+\frac{13}{2}$$

Ko te maha noa iti rawa atu o 10 me 2 ko 10. Me tahuri -\frac{1}{10} me \frac{13}{2} ki te hautau me te tautūnga 10.

$$-\frac{1}{10}+\frac{65}{10}$$

Tā te mea he rite te tauraro o -\frac{1}{10} me \frac{65}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1+65}{10}$$

Tāpirihia te -1 ki te 65, ka 64.

$$\frac{64}{10}$$

Whakahekea te hautanga \frac{64}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{32}{5}$$

Tauwehe

$$\frac{2 ^ {5}}{5} = 6\frac{2}{5} = 6.4$$
