Kua tāruatia ki te papatopenga
\frac{63+2}{3}-\frac{4\times 5+1}{5}
Whakareatia te 21 ki te 3, ka 63.
\frac{65}{3}-\frac{4\times 5+1}{5}
Tāpirihia te 63 ki te 2, ka 65.
\frac{65}{3}-\frac{20+1}{5}
Whakareatia te 4 ki te 5, ka 20.
\frac{65}{3}-\frac{21}{5}
Tāpirihia te 20 ki te 1, ka 21.
\frac{325}{15}-\frac{63}{15}
Ko te maha noa iti rawa atu o 3 me 5 ko 15. Me tahuri \frac{65}{3} me \frac{21}{5} ki te hautau me te tautūnga 15.
\frac{325-63}{15}
Tā te mea he rite te tauraro o \frac{325}{15} me \frac{63}{15}, me tango rāua mā te tango i ō raua taurunga.
\frac{262}{15}
Tangohia te 63 i te 325, ka 262.
