Ngā Upane Otinga

Tangohia te 3 i te 6, ka 3.

$$3^{2}-\left(9-4\right)^{2}+\left(5-2\right)^{2}$$

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

$$9-\left(9-4\right)^{2}+\left(5-2\right)^{2}$$

Tangohia te 4 i te 9, ka 5.

$$9-5^{2}+\left(5-2\right)^{2}$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$9-25+\left(5-2\right)^{2}$$

Tangohia te 25 i te 9, ka -16.

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

Tangohia te 2 i te 5, ka 3.

$$-16+3^{2}$$

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

$$-16+9$$

Tāpirihia te -16 ki te 9, ka -7.
