Whakaoti i te 12div2^2/3-1-(-9)

$$12 \div \frac { 2 ^ { 2 } } { 3 - 1 } - ( - 9 )$$

Aromātai

$$15$$

Ngā Upane Otinga

Whakawehe 12 ki te \frac{2^{2}}{3-1} mā te whakarea 12 ki te tau huripoki o \frac{2^{2}}{3-1}.

$$\frac{12\left(3-1\right)}{2^{2}}-\left(-9\right)$$

Tangohia te 1 i te 3, ka 2.

$$\frac{12\times 2}{2^{2}}-\left(-9\right)$$

Whakareatia te 12 ki te 2, ka 24.

$$\frac{24}{2^{2}}-\left(-9\right)$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$\frac{24}{4}-\left(-9\right)$$

Whakawehea te 24 ki te 4, kia riro ko 6.

$$6-\left(-9\right)$$

Ko te tauaro o -9 ko 9.

$$6+9$$

Tāpirihia te 6 ki te 9, ka 15.

$$15$$

Tauwehe

$$3\times 5$$
