Whakaoti i te 05+1+1-1/2+1=

$$05 + 1 + 1 - 1 / 2 + 1 =$$

Aromātai

$$\frac{5}{2}=2.5$$

Ngā Upane Otinga

Whakareatia te 0 ki te 5, ka 0.

$$0+1+1-\frac{1}{2}+1$$

Tāpirihia te 0 ki te 1, ka 1.

$$1+1-\frac{1}{2}+1$$

Tāpirihia te 1 ki te 1, ka 2.

$$2-\frac{1}{2}+1$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$\frac{4}{2}-\frac{1}{2}+1$$

Tā te mea he rite te tauraro o \frac{4}{2} me \frac{1}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4-1}{2}+1$$

Tangohia te 1 i te 4, ka 3.

$$\frac{3}{2}+1$$

Me tahuri te 1 ki te hautau \frac{2}{2}.

$$\frac{3}{2}+\frac{2}{2}$$

Tā te mea he rite te tauraro o \frac{3}{2} me \frac{2}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+2}{2}$$

Tāpirihia te 3 ki te 2, ka 5.

$$\frac{5}{2}$$

Tauwehe

$$\frac{5}{2} = 2\frac{1}{2} = 2.5$$
