Whakaoti i te 9-(6/7+7)+[2-1/2-(7-1/2)]+3

$$9 - ( \frac { 6 } { 7 } + 7 ) + [ 2 - \frac { 1 } { 2 } - ( 7 - \frac { 1 } { 2 } ) ] + 3$$

Aromātai

$$-\frac{6}{7}\approx -0.857142857$$

Ngā Upane Otinga

Me tahuri te 7 ki te hautau \frac{49}{7}.

$$9-\left(\frac{6}{7}+\frac{49}{7}\right)+2-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

Tā te mea he rite te tauraro o \frac{6}{7} me \frac{49}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$9-\frac{6+49}{7}+2-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

Tāpirihia te 6 ki te 49, ka 55.

$$9-\frac{55}{7}+2-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

Me tahuri te 9 ki te hautau \frac{63}{7}.

$$\frac{63}{7}-\frac{55}{7}+2-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

Tā te mea he rite te tauraro o \frac{63}{7} me \frac{55}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{63-55}{7}+2-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

Tangohia te 55 i te 63, ka 8.

$$\frac{8}{7}+2-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

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

$$\frac{8}{7}+\frac{4}{2}-\frac{1}{2}-\left(7-\frac{1}{2}\right)+3$$

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

$$\frac{8}{7}+\frac{4-1}{2}-\left(7-\frac{1}{2}\right)+3$$

Tangohia te 1 i te 4, ka 3.

$$\frac{8}{7}+\frac{3}{2}-\left(7-\frac{1}{2}\right)+3$$

Me tahuri te 7 ki te hautau \frac{14}{2}.

$$\frac{8}{7}+\frac{3}{2}-\left(\frac{14}{2}-\frac{1}{2}\right)+3$$

Tā te mea he rite te tauraro o \frac{14}{2} me \frac{1}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{8}{7}+\frac{3}{2}-\frac{14-1}{2}+3$$

Tangohia te 1 i te 14, ka 13.

$$\frac{8}{7}+\frac{3}{2}-\frac{13}{2}+3$$

Tā te mea he rite te tauraro o \frac{3}{2} me \frac{13}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{8}{7}+\frac{3-13}{2}+3$$

Tangohia te 13 i te 3, ka -10.

$$\frac{8}{7}+\frac{-10}{2}+3$$

Whakawehea te -10 ki te 2, kia riro ko -5.

$$\frac{8}{7}-5+3$$

Me tahuri te 5 ki te hautau \frac{35}{7}.

$$\frac{8}{7}-\frac{35}{7}+3$$

Tā te mea he rite te tauraro o \frac{8}{7} me \frac{35}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{8-35}{7}+3$$

Tangohia te 35 i te 8, ka -27.

$$-\frac{27}{7}+3$$

Me tahuri te 3 ki te hautau \frac{21}{7}.

$$-\frac{27}{7}+\frac{21}{7}$$

Tā te mea he rite te tauraro o -\frac{27}{7} me \frac{21}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-27+21}{7}$$

Tāpirihia te -27 ki te 21, ka -6.

$$-\frac{6}{7}$$

Tauwehe

$$-\frac{6}{7} = -0.8571428571428571$$
