Tuhia te \frac{\frac{\frac{6\times 5\times 4\times 3}{4}}{3}}{2} hei hautanga kotahi.

$$\frac{\frac{6\times 5\times 4\times 3}{4}}{3\times 2}$$

Me whakakore te 4 me te 4.

$$\frac{6\times 5\times 3}{3\times 2}$$

Whakareatia te 6 ki te 5, ka 30.

$$\frac{30\times 3}{3\times 2}$$

Whakareatia te 30 ki te 3, ka 90.

$$\frac{90}{3\times 2}$$

Whakareatia te 3 ki te 2, ka 6.

$$\frac{90}{6}$$

Whakawehea te 90 ki te 6, kia riro ko 15.
