\frac{100}{4}-\frac{-2}{-\frac{2}{3}}-2
Tātaihia te -2 mā te pū o 2, kia riro ko 4.
25-\frac{-2}{-\frac{2}{3}}-2
Whakawehea te 100 ki te 4, kia riro ko 25.
25-\left(-2\left(-\frac{3}{2}\right)\right)-2
Whakawehe -2 ki te -\frac{2}{3} mā te whakarea -2 ki te tau huripoki o -\frac{2}{3}.
25-3-2
Whakareatia -2 ki te -\frac{3}{2}.
22-2
Tangohia te 3 i te 25, ka 22.
20
Tangohia te 2 i te 22, ka 20.
