Whakaoti i te 3-4^2/2+2=

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

Aromātai

$$-\frac{9}{2}=-4.5$$

Ngā Upane Otinga

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

$$\frac{3-16}{2}+2$$

Tangohia te 16 i te 3, ka -13.

$$\frac{-13}{2}+2$$

Ka taea te hautanga \frac{-13}{2} te tuhi anō ko -\frac{13}{2} mā te tango i te tohu tōraro.

$$-\frac{13}{2}+2$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$-\frac{13}{2}+\frac{4}{2}$$

Tā te mea he rite te tauraro o -\frac{13}{2} me \frac{4}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-13+4}{2}$$

Tāpirihia te -13 ki te 4, ka -9.

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

Tauwehe

$$-\frac{9}{2} = -4\frac{1}{2} = -4.5$$
