Ka taea te hautanga \frac{-7}{11} te tuhi anō ko -\frac{7}{11} mā te tango i te tohu tōraro.

$$-\frac{7}{11}+\frac{13}{-15}+\frac{29}{25}$$

Ka taea te hautanga \frac{13}{-15} te tuhi anō ko -\frac{13}{15} mā te tango i te tohu tōraro.

$$-\frac{7}{11}-\frac{13}{15}+\frac{29}{25}$$

Ko te maha noa iti rawa atu o 11 me 15 ko 165. Me tahuri -\frac{7}{11} me \frac{13}{15} ki te hautau me te tautūnga 165.

$$-\frac{105}{165}-\frac{143}{165}+\frac{29}{25}$$

Tā te mea he rite te tauraro o -\frac{105}{165} me \frac{143}{165}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-105-143}{165}+\frac{29}{25}$$

Tangohia te 143 i te -105, ka -248.

$$-\frac{248}{165}+\frac{29}{25}$$

Ko te maha noa iti rawa atu o 165 me 25 ko 825. Me tahuri -\frac{248}{165} me \frac{29}{25} ki te hautau me te tautūnga 825.

$$-\frac{1240}{825}+\frac{957}{825}$$

Tā te mea he rite te tauraro o -\frac{1240}{825} me \frac{957}{825}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1240+957}{825}$$

Tāpirihia te -1240 ki te 957, ka -283.

$$-\frac{283}{825}$$
