Whakaoti i te 81/2+(-1/4)-5-5*0.25

$$8 \frac { 1 } { 2 } + ( - \frac { 1 } { 4 } ) - 5 - 5 \times 0.25$$

Aromātai

$$2$$

Ngā Upane Otinga

Whakareatia te 8 ki te 2, ka 16.

$$\frac{16+1}{2}-\frac{1}{4}-5-5\times 0.25$$

Tāpirihia te 16 ki te 1, ka 17.

$$\frac{17}{2}-\frac{1}{4}-5-5\times 0.25$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{17}{2} me \frac{1}{4} ki te hautau me te tautūnga 4.

$$\frac{34}{4}-\frac{1}{4}-5-5\times 0.25$$

Tā te mea he rite te tauraro o \frac{34}{4} me \frac{1}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{34-1}{4}-5-5\times 0.25$$

Tangohia te 1 i te 34, ka 33.

$$\frac{33}{4}-5-5\times 0.25$$

Me tahuri te 5 ki te hautau \frac{20}{4}.

$$\frac{33}{4}-\frac{20}{4}-5\times 0.25$$

Tā te mea he rite te tauraro o \frac{33}{4} me \frac{20}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{33-20}{4}-5\times 0.25$$

Tangohia te 20 i te 33, ka 13.

$$\frac{13}{4}-5\times 0.25$$

Whakareatia te 5 ki te 0.25, ka 1.25.

$$\frac{13}{4}-1.25$$

Me tahuri ki tau ā-ira 1.25 ki te hautau \frac{125}{100}. Whakahekea te hautanga \frac{125}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{13}{4}-\frac{5}{4}$$

Tā te mea he rite te tauraro o \frac{13}{4} me \frac{5}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{13-5}{4}$$

Tangohia te 5 i te 13, ka 8.

$$\frac{8}{4}$$

Whakawehea te 8 ki te 4, kia riro ko 2.
