Ngā Upane Otinga

Tangohia te 3 i te 1.7, ka -1.3.

$$\left(-1.3\right)^{2}-3|1.7-2|$$

Tātaihia te -1.3 mā te pū o 2, kia riro ko 1.69.

$$1.69-3|1.7-2|$$

Tangohia te 2 i te 1.7, ka -0.3.

$$1.69-3|-0.3|$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o -0.3 ko 0.3.

$$1.69-3\times 0.3$$

Whakareatia te 3 ki te 0.3, ka 0.9.

$$1.69-0.9$$

Tangohia te 0.9 i te 1.69, ka 0.79.

$$0.79$$

Tauwehe

$$\frac{79}{2 ^ {2} \cdot 5 ^ {2}} = 0.79$$
