5 raruraru e ōrite ana ki:
2 \frac { 1 } { 2 } \times ( 325 - 4 ) - 1821 \div ( - 3 )
Tohaina
Kua tāruatia ki te papatopenga
\frac{4+1}{2}\left(325-4\right)-\frac{1821}{-3}
Whakareatia te 2 ki te 2, ka 4.
\frac{5}{2}\left(325-4\right)-\frac{1821}{-3}
Tāpirihia te 4 ki te 1, ka 5.
\frac{5}{2}\times 321-\frac{1821}{-3}
Tangohia te 4 i te 325, ka 321.
\frac{5\times 321}{2}-\frac{1821}{-3}
Tuhia te \frac{5}{2}\times 321 hei hautanga kotahi.
\frac{1605}{2}-\frac{1821}{-3}
Whakareatia te 5 ki te 321, ka 1605.
\frac{1605}{2}-\left(-607\right)
Whakawehea te 1821 ki te -3, kia riro ko -607.
\frac{1605}{2}+607
Ko te tauaro o -607 ko 607.
\frac{1605}{2}+\frac{1214}{2}
Me tahuri te 607 ki te hautau \frac{1214}{2}.
\frac{1605+1214}{2}
Tā te mea he rite te tauraro o \frac{1605}{2} me \frac{1214}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{2819}{2}
Tāpirihia te 1605 ki te 1214, ka 2819.
