Ngā Upane Otinga

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

$$2\times 16+11\left(-2\right)^{3}+15\left(-2\right)^{2}-8\left(-2\right)-20$$

Whakareatia te 2 ki te 16, ka 32.

$$32+11\left(-2\right)^{3}+15\left(-2\right)^{2}-8\left(-2\right)-20$$

Tātaihia te -2 mā te pū o 3, kia riro ko -8.

$$32+11\left(-8\right)+15\left(-2\right)^{2}-8\left(-2\right)-20$$

Whakareatia te 11 ki te -8, ka -88.

$$32-88+15\left(-2\right)^{2}-8\left(-2\right)-20$$

Tangohia te 88 i te 32, ka -56.

$$-56+15\left(-2\right)^{2}-8\left(-2\right)-20$$

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

$$-56+15\times 4-8\left(-2\right)-20$$

Whakareatia te 15 ki te 4, ka 60.

$$-56+60-8\left(-2\right)-20$$

Tāpirihia te -56 ki te 60, ka 4.

$$4-8\left(-2\right)-20$$
