Ngā Upane Otinga

Tangohia te 5 i te 1, ka -4.

$$\frac{-3|-4|+2\left(3-5\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o -4 ko 4.

$$\frac{-3\times 4+2\left(3-5\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

Whakareatia te -3 ki te 4, ka -12.

$$\frac{-12+2\left(3-5\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

Tangohia te 5 i te 3, ka -2.

$$\frac{-12+2\left(-2\right)^{2}}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

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

$$\frac{-12+2\times 4}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

Whakareatia te 2 ki te 4, ka 8.

$$\frac{-12+8}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

Tāpirihia te -12 ki te 8, ka -4.

$$\frac{-4}{\left(4-8\right)^{2}+2\left(-1\right)^{15}}$$

Tangohia te 8 i te 4, ka -4.

$$\frac{-4}{\left(-4\right)^{2}+2\left(-1\right)^{15}}$$

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

$$\frac{-4}{16+2\left(-1\right)^{15}}$$

Tātaihia te -1 mā te pū o 15, kia riro ko -1.

$$\frac{-4}{16+2\left(-1\right)}$$

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

$$\frac{-4}{16-2}$$

Tangohia te 2 i te 16, ka 14.

$$\frac{-4}{14}$$

Whakahekea te hautanga \frac{-4}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
