Whakaoti i te (-025)*(-55)+1/4*(-35)-(-1/4)*2

$$( - 025 ) \times ( - 55 ) + \frac { 1 } { 4 } \times ( - 35 ) - ( - \frac { 1 } { 4 } ) \times 2$$

Aromātai

$$-\frac{33}{4}=-8.25$$

Ngā Upane Otinga

Whakareatia te 0 ki te 25, ka 0.

$$0\left(-55\right)+\frac{1}{4}\left(-35\right)-\left(-\frac{1}{4}\times 2\right)$$

Whakareatia te 0 ki te -55, ka 0.

$$0+\frac{1}{4}\left(-35\right)-\left(-\frac{1}{4}\times 2\right)$$

Whakareatia te \frac{1}{4} ki te -35, ka \frac{-35}{4}.

$$0+\frac{-35}{4}-\left(-\frac{1}{4}\times 2\right)$$

Ka taea te hautanga \frac{-35}{4} te tuhi anō ko -\frac{35}{4} mā te tango i te tohu tōraro.

$$0-\frac{35}{4}-\left(-\frac{1}{4}\times 2\right)$$

Tangohia te \frac{35}{4} i te 0, ka -\frac{35}{4}.

$$-\frac{35}{4}-\left(-\frac{1}{4}\times 2\right)$$

Tuhia te -\frac{1}{4}\times 2 hei hautanga kotahi.

$$-\frac{35}{4}-\frac{-2}{4}$$

Whakahekea te hautanga \frac{-2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{35}{4}-\left(-\frac{1}{2}\right)$$

Ko te tauaro o -\frac{1}{2} ko \frac{1}{2}.

$$-\frac{35}{4}+\frac{1}{2}$$

Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri -\frac{35}{4} me \frac{1}{2} ki te hautau me te tautūnga 4.

$$-\frac{35}{4}+\frac{2}{4}$$

Tā te mea he rite te tauraro o -\frac{35}{4} me \frac{2}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-35+2}{4}$$

Tāpirihia te -35 ki te 2, ka -33.

$$-\frac{33}{4}$$

Tauwehe

$$-\frac{33}{4} = -8\frac{1}{4} = -8.25$$
