Whakareatia te 25 ki te -0.125, ka -3.125.

$$-3.125\left(-4\right)\left(-\frac{4}{5}\right)\left(-8\right)\times \frac{4+1}{4}$$

Whakareatia te -3.125 ki te -4, ka 12.5.

$$12.5\left(-\frac{4}{5}\right)\left(-8\right)\times \frac{1\times 4+1}{4}$$

Me tahuri ki tau ā-ira 12.5 ki te hautau \frac{125}{10}. Whakahekea te hautanga \frac{125}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{25}{2}\left(-\frac{4}{5}\right)\left(-8\right)\times \frac{1\times 4+1}{4}$$

Me whakarea te \frac{25}{2} ki te -\frac{4}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25\left(-4\right)}{2\times 5}\left(-8\right)\times \frac{1\times 4+1}{4}$$

Mahia ngā whakarea i roto i te hautanga \frac{25\left(-4\right)}{2\times 5}.

$$\frac{-100}{10}\left(-8\right)\times \frac{1\times 4+1}{4}$$

Whakawehea te -100 ki te 10, kia riro ko -10.

$$-10\left(-8\right)\times \frac{4+1}{4}$$

Whakareatia te -10 ki te -8, ka 80.

$$80\times \frac{1\times 4+1}{4}$$

Whakareatia te 1 ki te 4, ka 4.

$$80\times \frac{4+1}{4}$$

Tāpirihia te 4 ki te 1, ka 5.

$$80\times \frac{5}{4}$$

Tuhia te 80\times \frac{5}{4} hei hautanga kotahi.

$$\frac{80\times 5}{4}$$

Whakareatia te 80 ki te 5, ka 400.

$$\frac{400}{4}$$

Whakawehea te 400 ki te 4, kia riro ko 100.

$$100$$
