Tangohia te 7 i te 4, ka -3.

$$2-3\left(-3\right)+2\left(-4-6+6\right)\left(-3-9\right)-2+5+7$$

Whakareatia te 3 ki te -3, ka -9.

$$2-\left(-9\right)+2\left(-4-6+6\right)\left(-3-9\right)-2+5+7$$

Ko te tauaro o -9 ko 9.

$$2+9+2\left(-4-6+6\right)\left(-3-9\right)-2+5+7$$

Tāpirihia te 2 ki te 9, ka 11.

$$11+2\left(-4-6+6\right)\left(-3-9\right)-2+5+7$$

Tangohia te 6 i te -4, ka -10.

$$11+2\left(-10+6\right)\left(-3-9\right)-2+5+7$$

Tāpirihia te -10 ki te 6, ka -4.

$$11+2\left(-4\right)\left(-3-9\right)-2+5+7$$

Whakareatia te 2 ki te -4, ka -8.

$$11-8\left(-3-9\right)-2+5+7$$

Tangohia te 9 i te -3, ka -12.

$$11-8\left(-12\right)-2+5+7$$

Whakareatia te -8 ki te -12, ka 96.

$$11+96-2+5+7$$

Tāpirihia te 11 ki te 96, ka 107.

$$107-2+5+7$$

Tangohia te 2 i te 107, ka 105.

$$105+5+7$$

Tāpirihia te 105 ki te 5, ka 110.

$$110+7$$

Tāpirihia te 110 ki te 7, ka 117.
