Ngā Upane Otinga

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

$$8+\frac{10}{2}+5\times 3+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Whakawehea te 10 ki te 2, kia riro ko 5.

$$8+5+5\times 3+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Tāpirihia te 8 ki te 5, ka 13.

$$13+5\times 3+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Whakareatia te 5 ki te 3, ka 15.

$$13+15+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Tāpirihia te 13 ki te 15, ka 28.

$$28+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Tāpirihia te 28 ki te 4, ka 32.

$$32-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Whakareatia te 5 ki te 2, ka 10.

$$32-10-8+4\times 2^{2}-\frac{20}{4}$$

Tangohia te 10 i te 32, ka 22.

$$22-8+4\times 2^{2}-\frac{20}{4}$$

Tangohia te 8 i te 22, ka 14.

$$14+4\times 2^{2}-\frac{20}{4}$$

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

$$14+4\times 4-\frac{20}{4}$$

Whakareatia te 4 ki te 4, ka 16.

$$14+16-\frac{20}{4}$$

Tāpirihia te 14 ki te 16, ka 30.

$$30-\frac{20}{4}$$

Whakawehea te 20 ki te 4, kia riro ko 5.

$$30-5$$

Tangohia te 5 i te 30, ka 25.
