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

$$|-4+\left(-2\right)^{3}-2^{-1}+\left(-2\right)^{-2}|$$

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

$$|-4-8-2^{-1}+\left(-2\right)^{-2}|$$

Tangohia te 8 i te -4, ka -12.

$$|-12-2^{-1}+\left(-2\right)^{-2}|$$

Tātaihia te 2 mā te pū o -1, kia riro ko \frac{1}{2}.

$$|-12-\frac{1}{2}+\left(-2\right)^{-2}|$$

Tangohia te \frac{1}{2} i te -12, ka -\frac{25}{2}.

$$|-\frac{25}{2}+\left(-2\right)^{-2}|$$

Tātaihia te -2 mā te pū o -2, kia riro ko \frac{1}{4}.

$$|-\frac{25}{2}+\frac{1}{4}|$$

Tāpirihia te -\frac{25}{2} ki te \frac{1}{4}, ka -\frac{49}{4}.

$$|-\frac{49}{4}|$$

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 -\frac{49}{4} ko \frac{49}{4}.

$$\frac{49}{4}$$

Tauwehe

$$\frac{7 ^ {2}}{2 ^ {2}} = 12\frac{1}{4} = 12.25$$
