Whakahekea te hautanga \frac{2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{2}-3-3+100$$

Me tahuri te 3 ki te hautau \frac{6}{2}.

$$\frac{1}{2}-\frac{6}{2}-3+100$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{6}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1-6}{2}-3+100$$

Tangohia te 6 i te 1, ka -5.

$$-\frac{5}{2}-3+100$$

Me tahuri te 3 ki te hautau \frac{6}{2}.

$$-\frac{5}{2}-\frac{6}{2}+100$$

Tā te mea he rite te tauraro o -\frac{5}{2} me \frac{6}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-5-6}{2}+100$$

Tangohia te 6 i te -5, ka -11.

$$-\frac{11}{2}+100$$

Me tahuri te 100 ki te hautau \frac{200}{2}.

$$-\frac{11}{2}+\frac{200}{2}$$

Tā te mea he rite te tauraro o -\frac{11}{2} me \frac{200}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-11+200}{2}$$

Tāpirihia te -11 ki te 200, ka 189.

$$\frac{189}{2}$$

Tauwehe

$$\frac{3 ^ {3} \cdot 7}{2} = 94\frac{1}{2} = 94.5$$
