Ngā Upane Otinga

Tangohia te 0.3 i te 1, ka 0.7.

$$75\left(2\left(0.7-0.5\right)+3\left(0.6-0.5+0.1\right)\right)$$

Tangohia te 0.5 i te 0.7, ka 0.2.

$$75\left(2\times 0.2+3\left(0.6-0.5+0.1\right)\right)$$

Whakareatia te 2 ki te 0.2, ka 0.4.

$$75\left(0.4+3\left(0.6-0.5+0.1\right)\right)$$

Tangohia te 0.5 i te 0.6, ka 0.1.

$$75\left(0.4+3\left(0.1+0.1\right)\right)$$

Tāpirihia te 0.1 ki te 0.1, ka 0.2.

$$75\left(0.4+3\times 0.2\right)$$

Whakareatia te 3 ki te 0.2, ka 0.6.

$$75\left(0.4+0.6\right)$$

Tāpirihia te 0.4 ki te 0.6, ka 1.

$$75\times 1$$

Whakareatia te 75 ki te 1, ka 75.
