Whakareatia te 3 ki te 2, ka 6.

$$15-3\left(100-4\left(6-5\times 5\right)+9\right)-23\times 6+6$$

Whakareatia te 5 ki te 5, ka 25.

$$15-3\left(100-4\left(6-25\right)+9\right)-23\times 6+6$$

Tangohia te 25 i te 6, ka -19.

$$15-3\left(100-4\left(-19\right)+9\right)-23\times 6+6$$

Whakareatia te 4 ki te -19, ka -76.

$$15-3\left(100-\left(-76\right)+9\right)-23\times 6+6$$

Ko te tauaro o -76 ko 76.

$$15-3\left(100+76+9\right)-23\times 6+6$$

Tāpirihia te 100 ki te 76, ka 176.

$$15-3\left(176+9\right)-23\times 6+6$$

Tāpirihia te 176 ki te 9, ka 185.

$$15-3\times 185-23\times 6+6$$

Whakareatia te 3 ki te 185, ka 555.

$$15-555-23\times 6+6$$

Tangohia te 555 i te 15, ka -540.

$$-540-23\times 6+6$$

Whakareatia te 23 ki te 6, ka 138.

$$-540-138+6$$

Tangohia te 138 i te -540, ka -678.

$$-678+6$$

Tāpirihia te -678 ki te 6, ka -672.
