Whakaoti i te 1125-6+-15^2div-2

$$1125-6+- { 15 }^{ 2 } \div -2$$

Aromātai

$$\frac{2463}{2}=1231.5$$

Ngā Upane Otinga

Tangohia te 6 i te 1125, ka 1119.

$$1119+\frac{-15^{2}}{-2}$$

Tātaihia te 15 mā te pū o 2, kia riro ko 225.

$$1119+\frac{-225}{-2}$$

Ka taea te hautanga \frac{-225}{-2} te whakamāmā ki te \frac{225}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$1119+\frac{225}{2}$$

Me tahuri te 1119 ki te hautau \frac{2238}{2}.

$$\frac{2238}{2}+\frac{225}{2}$$

Tā te mea he rite te tauraro o \frac{2238}{2} me \frac{225}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2238+225}{2}$$

Tāpirihia te 2238 ki te 225, ka 2463.

$$\frac{2463}{2}$$

Tauwehe

$$\frac{3 \cdot 821}{2} = 1231\frac{1}{2} = 1231.5$$
