Whakaoti i te 61/2-3*-3

$$6 \frac{ 1 }{ 2 } -3 \times -3$$

Aromātai

$$\frac{31}{2}=15.5$$

Ngā Upane Otinga

Whakareatia te 6 ki te 2, ka 12.

$$\frac{12+1}{2}-3\left(-3\right)$$

Tāpirihia te 12 ki te 1, ka 13.

$$\frac{13}{2}-3\left(-3\right)$$

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

$$\frac{13}{2}-\left(-9\right)$$

Ko te tauaro o -9 ko 9.

$$\frac{13}{2}+9$$

Me tahuri te 9 ki te hautau \frac{18}{2}.

$$\frac{13}{2}+\frac{18}{2}$$

Tā te mea he rite te tauraro o \frac{13}{2} me \frac{18}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{13+18}{2}$$

Tāpirihia te 13 ki te 18, ka 31.

$$\frac{31}{2}$$

Tauwehe

$$\frac{31}{2} = 15\frac{1}{2} = 15.5$$
