Ngā Upane Otinga

Tangohia te 18 i te 6, ka -12.

$$-\frac{1}{6}\left(-12\right)-12\times \frac{1}{3}$$

Tuhia te -\frac{1}{6}\left(-12\right) hei hautanga kotahi.

$$\frac{-\left(-12\right)}{6}-12\times \frac{1}{3}$$

Whakareatia te -1 ki te -12, ka 12.

$$\frac{12}{6}-12\times \frac{1}{3}$$

Whakawehea te 12 ki te 6, kia riro ko 2.

$$2-12\times \frac{1}{3}$$

Whakareatia te 12 ki te \frac{1}{3}, ka \frac{12}{3}.

$$2-\frac{12}{3}$$

Whakawehea te 12 ki te 3, kia riro ko 4.

$$2-4$$

Tangohia te 4 i te 2, ka -2.
