Ngā Upane Otinga

Whakareatia te 8.4 ki te 0.1, ka 0.84.

$$7-0.84+3\left(-4\times 0.25+3^{2}\right)+4.1+2$$

Tangohia te 0.84 i te 7, ka 6.16.

$$6.16+3\left(-4\times 0.25+3^{2}\right)+4.1+2$$

Whakareatia te -4 ki te 0.25, ka -1.

$$6.16+3\left(-1+3^{2}\right)+4.1+2$$

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

$$6.16+3\left(-1+9\right)+4.1+2$$

Tāpirihia te -1 ki te 9, ka 8.

$$6.16+3\times 8+4.1+2$$

Whakareatia te 3 ki te 8, ka 24.

$$6.16+24+4.1+2$$

Tāpirihia te 6.16 ki te 24, ka 30.16.

$$30.16+4.1+2$$

Tāpirihia te 30.16 ki te 4.1, ka 34.26.

$$34.26+2$$

Tāpirihia te 34.26 ki te 2, ka 36.26.

$$36.26$$

Tauwehe

$$\frac{37 \cdot 7 ^ {2}}{2 \cdot 5 ^ {2}} = 36\frac{13}{50} = 36.26$$
