Whakaoti i te 1/2-2^33^2+3-2^24^2

$$\frac{ 1 }{ 2 } - { 2 }^{ 3 } { 3 }^{ 2 } +3- { 2 }^{ 2 } { 4 }^{ 2 }$$

Aromātai

$$-\frac{265}{2}=-132.5$$

Ngā Upane Otinga

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

$$\frac{1}{2}-8\times 3^{2}+3-2^{2}\times 4^{2}$$

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

$$\frac{1}{2}-8\times 9+3-2^{2}\times 4^{2}$$

Whakareatia te 8 ki te 9, ka 72.

$$\frac{1}{2}-72+3-2^{2}\times 4^{2}$$

Me tahuri te 72 ki te hautau \frac{144}{2}.

$$\frac{1}{2}-\frac{144}{2}+3-2^{2}\times 4^{2}$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{144}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1-144}{2}+3-2^{2}\times 4^{2}$$

Tangohia te 144 i te 1, ka -143.

$$-\frac{143}{2}+3-2^{2}\times 4^{2}$$

Me tahuri te 3 ki te hautau \frac{6}{2}.

$$-\frac{143}{2}+\frac{6}{2}-2^{2}\times 4^{2}$$

Tā te mea he rite te tauraro o -\frac{143}{2} me \frac{6}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-143+6}{2}-2^{2}\times 4^{2}$$

Tāpirihia te -143 ki te 6, ka -137.

$$-\frac{137}{2}-2^{2}\times 4^{2}$$

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

$$-\frac{137}{2}-4\times 4^{2}$$

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

$$-\frac{137}{2}-4\times 16$$

Whakareatia te 4 ki te 16, ka 64.

$$-\frac{137}{2}-64$$

Me tahuri te 64 ki te hautau \frac{128}{2}.

$$-\frac{137}{2}-\frac{128}{2}$$

Tā te mea he rite te tauraro o -\frac{137}{2} me \frac{128}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-137-128}{2}$$

Tangohia te 128 i te -137, ka -265.

$$-\frac{265}{2}$$

Tauwehe

$$-\frac{265}{2} = -132\frac{1}{2} = -132.5$$
