Whakaoti i te -31/2|-(-3)=

$$- 3 \frac { 1 } { 2 } | - ( - 3 ) =$$

Aromātai

$$-\frac{21}{2}=-10.5$$

Ngā Upane Otinga

Whakareatia te 3 ki te 2, ka 6.

$$\left(-\frac{6+1}{2}\right)|-\left(-3\right)|$$

Tāpirihia te 6 ki te 1, ka 7.

$$-\frac{7}{2}|-\left(-3\right)|$$

Ko te tauaro o -3 ko 3.

$$-\frac{7}{2}|3|$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o 3 ko 3.

$$-\frac{7}{2}\times 3$$

Tuhia te -\frac{7}{2}\times 3 hei hautanga kotahi.

$$\frac{-7\times 3}{2}$$

Whakareatia te -7 ki te 3, ka -21.

$$\frac{-21}{2}$$

Ka taea te hautanga \frac{-21}{2} te tuhi anō ko -\frac{21}{2} mā te tango i te tohu tōraro.

$$-\frac{21}{2}$$

Tauwehe

$$-\frac{21}{2} = -10\frac{1}{2} = -10.5$$
