Whakareatia te 25 ki te 2, ka 50. Whakareatia te 10 ki te 5, ka 50. Whakareatia te 9 ki te 8, ka 72.

$$50+50+72+56+3\left(5+6\left(3\times 4-10\right)-17\right)-5\times 4$$

Tāpirihia te 50 ki te 50, ka 100.

$$100+72+56+3\left(5+6\left(3\times 4-10\right)-17\right)-5\times 4$$

Tāpirihia te 100 ki te 72, ka 172.

$$172+56+3\left(5+6\left(3\times 4-10\right)-17\right)-5\times 4$$

Whakareatia te 3 ki te 4, ka 12.

$$172+56+3\left(5+6\left(12-10\right)-17\right)-5\times 4$$

Tangohia te 10 i te 12, ka 2.

$$172+56+3\left(5+6\times 2-17\right)-5\times 4$$

Whakareatia te 6 ki te 2, ka 12.

$$172+56+3\left(5+12-17\right)-5\times 4$$

Tāpirihia te 5 ki te 12, ka 17.

$$172+56+3\left(17-17\right)-5\times 4$$

Tangohia te 17 i te 17, ka 0.

$$172+56+3\times 0-5\times 4$$

Whakareatia te 3 ki te 0, ka 0.

$$172+56+0-5\times 4$$

Tāpirihia te 56 ki te 0, ka 56.

$$172+56-5\times 4$$

Whakareatia te 5 ki te 4, ka 20.

$$172+56-20$$

Tangohia te 20 i te 56, ka 36.

$$172+36$$

Tāpirihia te 172 ki te 36, ka 208.
