Kua tāruatia ki te papatopenga
4-4\left(-\frac{1}{5}\right)\times 4
Tātaihia te 2 mā te pū o 2, kia riro ko 4.
4-\frac{4\left(-1\right)}{5}\times 4
Tuhia te 4\left(-\frac{1}{5}\right) hei hautanga kotahi.
4-\frac{-4}{5}\times 4
Whakareatia te 4 ki te -1, ka -4.
4-\left(-\frac{4}{5}\times 4\right)
Ka taea te hautanga \frac{-4}{5} te tuhi anō ko -\frac{4}{5} mā te tango i te tohu tōraro.
4-\frac{-4\times 4}{5}
Tuhia te -\frac{4}{5}\times 4 hei hautanga kotahi.
4-\frac{-16}{5}
Whakareatia te -4 ki te 4, ka -16.
4-\left(-\frac{16}{5}\right)
Ka taea te hautanga \frac{-16}{5} te tuhi anō ko -\frac{16}{5} mā te tango i te tohu tōraro.
4+\frac{16}{5}
Ko te tauaro o -\frac{16}{5} ko \frac{16}{5}.
\frac{20}{5}+\frac{16}{5}
Me tahuri te 4 ki te hautau \frac{20}{5}.
\frac{20+16}{5}
Tā te mea he rite te tauraro o \frac{20}{5} me \frac{16}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{36}{5}
Tāpirihia te 20 ki te 16, ka 36.
