-5+\frac{8\left(-1\right)}{4}-\frac{9}{-\frac{1}{3}}
Tuhia te 8\left(-\frac{1}{4}\right) hei hautanga kotahi.
-5+\frac{-8}{4}-\frac{9}{-\frac{1}{3}}
Whakareatia te 8 ki te -1, ka -8.
-5-2-\frac{9}{-\frac{1}{3}}
Whakawehea te -8 ki te 4, kia riro ko -2.
-7-\frac{9}{-\frac{1}{3}}
Tangohia te 2 i te -5, ka -7.
-7-9\left(-3\right)
Whakawehe 9 ki te -\frac{1}{3} mā te whakarea 9 ki te tau huripoki o -\frac{1}{3}.
-7-\left(-27\right)
Whakareatia te 9 ki te -3, ka -27.
-7+27
Ko te tauaro o -27 ko 27.
20
Tāpirihia te -7 ki te 27, ka 20.
