Whakaoti i te 21/2+48div(-2)+(-73/5)=

$$2 \frac{ 1 }{ 2 } +48 \div (-2)+(-7 \frac{ 3 }{ 5 } )=$$

Aromātai

$$-\frac{291}{10}=-29.1$$

Ngā Upane Otinga

Whakareatia te 2 ki te 2, ka 4.

$$\frac{4+1}{2}+\frac{48}{-2}-\frac{7\times 5+3}{5}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{5}{2}+\frac{48}{-2}-\frac{7\times 5+3}{5}$$

Whakawehea te 48 ki te -2, kia riro ko -24.

$$\frac{5}{2}-24-\frac{7\times 5+3}{5}$$

Me tahuri te 24 ki te hautau \frac{48}{2}.

$$\frac{5}{2}-\frac{48}{2}-\frac{7\times 5+3}{5}$$

Tā te mea he rite te tauraro o \frac{5}{2} me \frac{48}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{5-48}{2}-\frac{7\times 5+3}{5}$$

Tangohia te 48 i te 5, ka -43.

$$-\frac{43}{2}-\frac{7\times 5+3}{5}$$

Whakareatia te 7 ki te 5, ka 35.

$$-\frac{43}{2}-\frac{35+3}{5}$$

Tāpirihia te 35 ki te 3, ka 38.

$$-\frac{43}{2}-\frac{38}{5}$$

Ko te maha noa iti rawa atu o 2 me 5 ko 10. Me tahuri -\frac{43}{2} me \frac{38}{5} ki te hautau me te tautūnga 10.

$$-\frac{215}{10}-\frac{76}{10}$$

Tā te mea he rite te tauraro o -\frac{215}{10} me \frac{76}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-215-76}{10}$$

Tangohia te 76 i te -215, ka -291.

$$-\frac{291}{10}$$

Tauwehe

$$-\frac{291}{10} = -29\frac{1}{10} = -29.1$$
