Kua tāruatia ki te papatopenga
1.75-\left(-\frac{7+2}{7}\right)\times 6.5\times \frac{7}{9}
Whakareatia te 1 ki te 7, ka 7.
1.75-\left(-\frac{9}{7}\times 6.5\times \frac{7}{9}\right)
Tāpirihia te 7 ki te 2, ka 9.
1.75-\left(-\frac{9}{7}\times \frac{13}{2}\times \frac{7}{9}\right)
Me tahuri ki tau ā-ira 6.5 ki te hautau \frac{65}{10}. Whakahekea te hautanga \frac{65}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
1.75-\frac{-9\times 13}{7\times 2}\times \frac{7}{9}
Me whakarea te -\frac{9}{7} ki te \frac{13}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
1.75-\frac{-117}{14}\times \frac{7}{9}
Mahia ngā whakarea i roto i te hautanga \frac{-9\times 13}{7\times 2}.
1.75-\left(-\frac{117}{14}\times \frac{7}{9}\right)
Ka taea te hautanga \frac{-117}{14} te tuhi anō ko -\frac{117}{14} mā te tango i te tohu tōraro.
1.75-\frac{-117\times 7}{14\times 9}
Me whakarea te -\frac{117}{14} ki te \frac{7}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
1.75-\frac{-819}{126}
Mahia ngā whakarea i roto i te hautanga \frac{-117\times 7}{14\times 9}.
1.75-\left(-\frac{13}{2}\right)
Whakahekea te hautanga \frac{-819}{126} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 63.
1.75+\frac{13}{2}
Ko te tauaro o -\frac{13}{2} ko \frac{13}{2}.
\frac{7}{4}+\frac{13}{2}
Me tahuri ki tau ā-ira 1.75 ki te hautau \frac{175}{100}. Whakahekea te hautanga \frac{175}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
\frac{7}{4}+\frac{26}{4}
Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{7}{4} me \frac{13}{2} ki te hautau me te tautūnga 4.
\frac{7+26}{4}
Tā te mea he rite te tauraro o \frac{7}{4} me \frac{26}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{33}{4}
Tāpirihia te 7 ki te 26, ka 33.
