Whakaoti i te -3^2+(4-9)^2/7-2*6

$$\frac { - 3 ^ { 2 } + ( 4 - 9 ) ^ { 2 } } { 7 - 2 \cdot 6 }$$

Aromātai

$$-\frac{16}{5}=-3.2$$

Ngā Upane Otinga

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{-9+\left(4-9\right)^{2}}{7-2\times 6}$$

Tangohia te 9 i te 4, ka -5.

$$\frac{-9+\left(-5\right)^{2}}{7-2\times 6}$$

Tātaihia te -5 mā te pū o 2, kia riro ko 25.

$$\frac{-9+25}{7-2\times 6}$$

Tāpirihia te -9 ki te 25, ka 16.

$$\frac{16}{7-2\times 6}$$

Whakareatia te 2 ki te 6, ka 12.

$$\frac{16}{7-12}$$

Tangohia te 12 i te 7, ka -5.

$$\frac{16}{-5}$$

Ka taea te hautanga \frac{16}{-5} te tuhi anō ko -\frac{16}{5} mā te tango i te tohu tōraro.

$$-\frac{16}{5}$$

Tauwehe

$$-\frac{16}{5} = -3\frac{1}{5} = -3.2$$
