Ngā Upane Otinga

Tangohia te 5 i te 7, ka 2.

$$\frac{-3\times 2+2\left(3-5\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{5}}$$

Whakareatia te -3 ki te 2, ka -6.

$$\frac{-6+2\left(3-5\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{5}}$$

Tangohia te 5 i te 3, ka -2.

$$\frac{-6+2\left(-2\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{5}}$$

Tātaihia te -2 mā te pū o 2, kia riro ko 4.

$$\frac{-6+2\times 4}{\left(4-8\right)^{2}+2\left(-1\right)^{5}}$$

Whakareatia te 2 ki te 4, ka 8.

$$\frac{-6+8}{\left(4-8\right)^{2}+2\left(-1\right)^{5}}$$

Tāpirihia te -6 ki te 8, ka 2.

$$\frac{2}{\left(4-8\right)^{2}+2\left(-1\right)^{5}}$$

Tangohia te 8 i te 4, ka -4.

$$\frac{2}{\left(-4\right)^{2}+2\left(-1\right)^{5}}$$

Tātaihia te -4 mā te pū o 2, kia riro ko 16.

$$\frac{2}{16+2\left(-1\right)^{5}}$$

Tātaihia te -1 mā te pū o 5, kia riro ko -1.

$$\frac{2}{16+2\left(-1\right)}$$

Whakareatia te 2 ki te -1, ka -2.

$$\frac{2}{16-2}$$

Tangohia te 2 i te 16, ka 14.

$$\frac{2}{14}$$

Whakahekea te hautanga \frac{2}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
