Whakaoti i te [0-1/2(1)^2]+[1/22^2-0]=

$$[ 0 - \frac { 1 } { 2 } ( 1 ) ^ { 2 } ] + [ \frac { 1 } { 2 } 2 ^ { 2 } - 0 ] =$$

Aromātai

$$\frac{3}{2}=1.5$$

Ngā Upane Otinga

Tātaihia te 1 mā te pū o 2, kia riro ko 1.

$$0-\frac{1}{2}\times 1+\frac{1}{2}\times 2^{2}-0$$

Whakareatia te \frac{1}{2} ki te 1, ka \frac{1}{2}.

$$0-\frac{1}{2}+\frac{1}{2}\times 2^{2}-0$$

Tangohia te \frac{1}{2} i te 0, ka -\frac{1}{2}.

$$-\frac{1}{2}+\frac{1}{2}\times 2^{2}-0$$

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

$$-\frac{1}{2}+\frac{1}{2}\times 4-0$$

Whakareatia te \frac{1}{2} ki te 4, ka \frac{4}{2}.

$$-\frac{1}{2}+\frac{4}{2}-0$$

Whakawehea te 4 ki te 2, kia riro ko 2.

$$-\frac{1}{2}+2-0$$

Tangohia te 0 i te 2, ka 2.

$$-\frac{1}{2}+2$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$-\frac{1}{2}+\frac{4}{2}$$

Tā te mea he rite te tauraro o -\frac{1}{2} me \frac{4}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1+4}{2}$$

Tāpirihia te -1 ki te 4, ka 3.

$$\frac{3}{2}$$

Tauwehe

$$\frac{3}{2} = 1\frac{1}{2} = 1.5$$
