Whakaoti i te (-6)+5*(-7)-(-42)div(-9)

$$( - 6 ) + 5 \times ( - 7 ) - ( - 42 ) \div ( - 9 )$$

Aromātai

$$-\frac{137}{3}\approx -45.666666667$$

Ngā Upane Otinga

Whakareatia te 5 ki te -7, ka -35.

$$-6-35-\frac{-42}{-9}$$

Tangohia te 35 i te -6, ka -41.

$$-41-\frac{-42}{-9}$$

Whakahekea te hautanga \frac{-42}{-9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.

$$-41-\frac{14}{3}$$

Me tahuri te -41 ki te hautau -\frac{123}{3}.

$$-\frac{123}{3}-\frac{14}{3}$$

Tā te mea he rite te tauraro o -\frac{123}{3} me \frac{14}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-123-14}{3}$$

Tangohia te 14 i te -123, ka -137.

$$-\frac{137}{3}$$

Tauwehe

$$-\frac{137}{3} = -45\frac{2}{3} = -45.666666666666664$$
