Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 4 i te 9, ka 5.

$$A=5+6-11-\left(-8+3-2\right)$$

Tāpirihia te 5 ki te 6, ka 11.

$$A=11-11-\left(-8+3-2\right)$$

Tangohia te 11 i te 11, ka 0.

$$A=0-\left(-8+3-2\right)$$

Tāpirihia te -8 ki te 3, ka -5.

$$A=0-\left(-5-2\right)$$

Tangohia te 2 i te -5, ka -7.

$$A=0-\left(-7\right)$$

Ko te tauaro o -7 ko 7.

$$A=0+7$$

Tāpirihia te 0 ki te 7, ka 7.

$$A=7$$

Whakaarohia te whārite tuarua. Tangohia te 15 i te 7, ka -8.

$$B=-16-\left(-8+4\right)-\left(-5+12\right)$$

Tāpirihia te -8 ki te 4, ka -4.

$$B=-16-\left(-4\right)-\left(-5+12\right)$$

Ko te tauaro o -4 ko 4.

$$B=-16+4-\left(-5+12\right)$$

Tāpirihia te -16 ki te 4, ka -12.

$$B=-12-\left(-5+12\right)$$

Tāpirihia te -5 ki te 12, ka 7.

$$B=-12-7$$

Tangohia te 7 i te -12, ka -19.

$$B=-19$$

Whakaarohia te whārite tuatoru. Tangohia te 5 i te 7, ka 2.

$$C=2+2-3-\left(-7+5-3\right)$$

Tāpirihia te 2 ki te 2, ka 4.

$$C=4-3-\left(-7+5-3\right)$$

Tangohia te 3 i te 4, ka 1.

$$C=1-\left(-7+5-3\right)$$

Tāpirihia te -7 ki te 5, ka -2.

$$C=1-\left(-2-3\right)$$

Tangohia te 3 i te -2, ka -5.

$$C=1-\left(-5\right)$$

Ko te tauaro o -5 ko 5.

$$C=1+5$$

Tāpirihia te 1 ki te 5, ka 6.

$$C=6$$

Kua oti te pūnaha te whakatau.

$$A=7 B=-19 C=6$$
