Ngā Upane Otinga

Tangohia te 10 i te 2, ka -8.

$$-\left(-\left(-\left(-\left(-8\right)+1\right)-6\left(-2+1\right)\right)-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Ko te tauaro o -8 ko 8.

$$-\left(-\left(-\left(8+1\right)-6\left(-2+1\right)\right)-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Tāpirihia te 8 ki te 1, ka 9.

$$-\left(-\left(-9-6\left(-2+1\right)\right)-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Tāpirihia te -2 ki te 1, ka -1.

$$-\left(-\left(-9-6\left(-1\right)\right)-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Whakareatia te -6 ki te -1, ka 6.

$$-\left(-\left(-9+6\right)-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Tāpirihia te -9 ki te 6, ka -3.

$$-\left(-\left(-3\right)-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Ko te tauaro o -3 ko 3.

$$-\left(3-8\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Tangohia te 8 i te 3, ka -5.

$$-\left(-5\right)-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Ko te tauaro o -5 ko 5.

$$5-1-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Tangohia te 1 i te 5, ka 4.

$$4-\left(2-3\right)+4-5-2+1-\left(7-3\right)-9+20$$

Tangohia te 3 i te 2, ka -1.

$$4-\left(-1\right)+4-5-2+1-\left(7-3\right)-9+20$$

Ko te tauaro o -1 ko 1.

$$4+1+4-5-2+1-\left(7-3\right)-9+20$$

Tāpirihia te 4 ki te 1, ka 5.

$$5+4-5-2+1-\left(7-3\right)-9+20$$

Tāpirihia te 5 ki te 4, ka 9.

$$9-5-2+1-\left(7-3\right)-9+20$$

Tangohia te 5 i te 9, ka 4.

$$4-2+1-\left(7-3\right)-9+20$$

Tangohia te 2 i te 4, ka 2.

$$2+1-\left(7-3\right)-9+20$$

Tāpirihia te 2 ki te 1, ka 3.

$$3-\left(7-3\right)-9+20$$

Tangohia te 3 i te 7, ka 4.

$$3-4-9+20$$

Tangohia te 4 i te 3, ka -1.

$$-1-9+20$$

Tangohia te 9 i te -1, ka -10.

$$-10+20$$

Tāpirihia te -10 ki te 20, ka 10.
