Ngā Upane Otinga

Whakareatia te 84 ki te 0, ka 0.

$$0\times 1+3\left(-4\times 0\times 25+3^{2}\right)+\frac{41}{2}$$

Whakareatia te 0 ki te 1, ka 0.

$$0+3\left(-4\times 0\times 25+3^{2}\right)+\frac{41}{2}$$

Whakareatia te -4 ki te 0, ka 0.

$$0+3\left(0\times 25+3^{2}\right)+\frac{41}{2}$$

Whakareatia te 0 ki te 25, ka 0.

$$0+3\left(0+3^{2}\right)+\frac{41}{2}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$0+3\left(0+9\right)+\frac{41}{2}$$

Tāpirihia te 0 ki te 9, ka 9.

$$0+3\times 9+\frac{41}{2}$$

Whakareatia te 3 ki te 9, ka 27.

$$0+27+\frac{41}{2}$$

Tāpirihia te 0 ki te 27, ka 27.

$$27+\frac{41}{2}$$

Me tahuri te 27 ki te hautau \frac{54}{2}.

$$\frac{54}{2}+\frac{41}{2}$$

Tā te mea he rite te tauraro o \frac{54}{2} me \frac{41}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{54+41}{2}$$

Tāpirihia te 54 ki te 41, ka 95.

$$\frac{95}{2}$$

Tauwehe

$$\frac{5 \cdot 19}{2} = 47\frac{1}{2} = 47.5$$
