Whakaoti i te 1/2-2^3*3^2+3-2^2*4

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

Aromātai

$$-\frac{169}{2}=-84.5$$

Ngā Upane Otinga

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

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

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

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

Whakareatia te 8 ki te 9, ka 72.

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

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

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

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.

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

Tangohia te 144 i te 1, ka -143.

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

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

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

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.

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

Tāpirihia te -143 ki te 6, ka -137.

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

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

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

Whakareatia te 4 ki te 4, ka 16.

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

Me tahuri te 16 ki te hautau \frac{32}{2}.

$$-\frac{137}{2}-\frac{32}{2}$$

Tā te mea he rite te tauraro o -\frac{137}{2} me \frac{32}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-137-32}{2}$$

Tangohia te 32 i te -137, ka -169.

$$-\frac{169}{2}$$

Tauwehe

$$-\frac{169}{2} = -84\frac{1}{2} = -84.5$$
