Tohaina
Kua tāruatia ki te papatopenga
0.8\left(6-\frac{3^{3}}{9}\right)-5
Tātaitia te pūtakerua o 36 kia tae ki 6.
0.8\left(6-\frac{27}{9}\right)-5
Tātaihia te 3 mā te pū o 3, kia riro ko 27.
0.8\left(6-3\right)-5
Whakawehea te 27 ki te 9, kia riro ko 3.
0.8\times 3-5
Tangohia te 3 i te 6, ka 3.
2.4-5
Whakareatia te 0.8 ki te 3, ka 2.4.
-2.6
Tangohia te 5 i te 2.4, ka -2.6.
