Whakaoti i te (-2)^3-3*[(-4)^2+2]-(-3)^2div(-2)

$$( - 2 ) ^ { 3 } - 3 \times [ ( - 4 ) ^ { 2 } + 2 ] - ( - 3 ) ^ { 2 } \div ( - 2 )$$

Aromātai

$$-\frac{115}{2}=-57.5$$

Ngā Upane Otinga

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

$$-8-3\left(\left(-4\right)^{2}+2\right)-\frac{\left(-3\right)^{2}}{-2}$$

Tātaihia te -4 mā te pū o 2, kia riro ko 16.

$$-8-3\left(16+2\right)-\frac{\left(-3\right)^{2}}{-2}$$

Tāpirihia te 16 ki te 2, ka 18.

$$-8-3\times 18-\frac{\left(-3\right)^{2}}{-2}$$

Whakareatia te 3 ki te 18, ka 54.

$$-8-54-\frac{\left(-3\right)^{2}}{-2}$$

Tangohia te 54 i te -8, ka -62.

$$-62-\frac{\left(-3\right)^{2}}{-2}$$

Tātaihia te -3 mā te pū o 2, kia riro ko 9.

$$-62-\frac{9}{-2}$$

Ka taea te hautanga \frac{9}{-2} te tuhi anō ko -\frac{9}{2} mā te tango i te tohu tōraro.

$$-62-\left(-\frac{9}{2}\right)$$

Ko te tauaro o -\frac{9}{2} ko \frac{9}{2}.

$$-62+\frac{9}{2}$$

Me tahuri te -62 ki te hautau -\frac{124}{2}.

$$-\frac{124}{2}+\frac{9}{2}$$

Tā te mea he rite te tauraro o -\frac{124}{2} me \frac{9}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-124+9}{2}$$

Tāpirihia te -124 ki te 9, ka -115.

$$-\frac{115}{2}$$

Tauwehe

$$-\frac{115}{2} = -57\frac{1}{2} = -57.5$$
