Whakaoti i te 2-{1/2:4-6^0+[5+(2^2:0.3)]}

$$2 - \{ \frac { 1 } { 2 } : 4 - 6 ^ { 0 } + [ 5 + ( 2 ^ { 2 } : 0.3 ) ] \}$$

Aromātai

$$-\frac{371}{24}\approx -15.458333333$$

Ngā Upane Otinga

Tuhia te \frac{\frac{1}{2}}{4} hei hautanga kotahi.

$$2-\left(\frac{1}{2\times 4}-6^{0}+5+\frac{2^{2}}{0.3}\right)$$

Whakareatia te 2 ki te 4, ka 8.

$$2-\left(\frac{1}{8}-6^{0}+5+\frac{2^{2}}{0.3}\right)$$

Tātaihia te 6 mā te pū o 0, kia riro ko 1.

$$2-\left(\frac{1}{8}-1+5+\frac{2^{2}}{0.3}\right)$$

Tangohia te 1 i te \frac{1}{8}, ka -\frac{7}{8}.

$$2-\left(-\frac{7}{8}+5+\frac{2^{2}}{0.3}\right)$$

Tāpirihia te -\frac{7}{8} ki te 5, ka \frac{33}{8}.

$$2-\left(\frac{33}{8}+\frac{2^{2}}{0.3}\right)$$

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

$$2-\left(\frac{33}{8}+\frac{4}{0.3}\right)$$

Whakarohaina te \frac{4}{0.3} mā te whakarea i te taurunga me te tauraro ki te 10.

$$2-\left(\frac{33}{8}+\frac{40}{3}\right)$$

Tāpirihia te \frac{33}{8} ki te \frac{40}{3}, ka \frac{419}{24}.

$$2-\frac{419}{24}$$

Tangohia te \frac{419}{24} i te 2, ka -\frac{371}{24}.

$$-\frac{371}{24}$$

Tauwehe

$$-\frac{371}{24} = -15\frac{11}{24} = -15.458333333333334$$
