Whakaoti i te 13*9+711:4*2+101-40^2

$$13 \times 9 + 711 : 4 \times 2 + 101 - 40 ^ { 2 }$$

Aromātai

$$-\frac{2053}{2}=-1026.5$$

Ngā Upane Otinga

Whakareatia te 13 ki te 9, ka 117.

$$117+\frac{711}{4}\times 2+101-40^{2}$$

Tuhia te \frac{711}{4}\times 2 hei hautanga kotahi.

$$117+\frac{711\times 2}{4}+101-40^{2}$$

Whakareatia te 711 ki te 2, ka 1422.

$$117+\frac{1422}{4}+101-40^{2}$$

Whakahekea te hautanga \frac{1422}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$117+\frac{711}{2}+101-40^{2}$$

Me tahuri te 117 ki te hautau \frac{234}{2}.

$$\frac{234}{2}+\frac{711}{2}+101-40^{2}$$

Tā te mea he rite te tauraro o \frac{234}{2} me \frac{711}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{234+711}{2}+101-40^{2}$$

Tāpirihia te 234 ki te 711, ka 945.

$$\frac{945}{2}+101-40^{2}$$

Me tahuri te 101 ki te hautau \frac{202}{2}.

$$\frac{945}{2}+\frac{202}{2}-40^{2}$$

Tā te mea he rite te tauraro o \frac{945}{2} me \frac{202}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{945+202}{2}-40^{2}$$

Tāpirihia te 945 ki te 202, ka 1147.

$$\frac{1147}{2}-40^{2}$$

Tātaihia te 40 mā te pū o 2, kia riro ko 1600.

$$\frac{1147}{2}-1600$$

Me tahuri te 1600 ki te hautau \frac{3200}{2}.

$$\frac{1147}{2}-\frac{3200}{2}$$

Tā te mea he rite te tauraro o \frac{1147}{2} me \frac{3200}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1147-3200}{2}$$

Tangohia te 3200 i te 1147, ka -2053.

$$-\frac{2053}{2}$$

Tauwehe

$$-\frac{2053}{2} = -1026\frac{1}{2} = -1026.5$$
