Aromātai

$$-\frac{29}{7}\approx -4.142857143$$

Ngā Upane Otinga

Tuhia te \frac{5}{7}\times 3 hei hautanga kotahi.

$$3-\left(5-\left(2-\left(2+\frac{5\times 3}{7}\right)\right)\right)$$

Whakareatia te 5 ki te 3, ka 15.

$$3-\left(5-\left(2-\left(2+\frac{15}{7}\right)\right)\right)$$

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

$$3-\left(5-\left(2-\left(\frac{14}{7}+\frac{15}{7}\right)\right)\right)$$

Tā te mea he rite te tauraro o \frac{14}{7} me \frac{15}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$3-\left(5-\left(2-\frac{14+15}{7}\right)\right)$$

Tāpirihia te 14 ki te 15, ka 29.

$$3-\left(5-\left(2-\frac{29}{7}\right)\right)$$

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

$$3-\left(5-\left(\frac{14}{7}-\frac{29}{7}\right)\right)$$

Tā te mea he rite te tauraro o \frac{14}{7} me \frac{29}{7}, me tango rāua mā te tango i ō raua taurunga.

$$3-\left(5-\frac{14-29}{7}\right)$$

Tangohia te 29 i te 14, ka -15.

$$3-\left(5-\left(-\frac{15}{7}\right)\right)$$

Ko te tauaro o -\frac{15}{7} ko \frac{15}{7}.

$$3-\left(5+\frac{15}{7}\right)$$

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

$$3-\left(\frac{35}{7}+\frac{15}{7}\right)$$

Tā te mea he rite te tauraro o \frac{35}{7} me \frac{15}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$3-\frac{35+15}{7}$$

Tāpirihia te 35 ki te 15, ka 50.

$$3-\frac{50}{7}$$

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

$$\frac{21}{7}-\frac{50}{7}$$

Tā te mea he rite te tauraro o \frac{21}{7} me \frac{50}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{21-50}{7}$$

Tangohia te 50 i te 21, ka -29.

$$-\frac{29}{7}$$

Tauwehe

$$-\frac{29}{7} = -4\frac{1}{7} = -4.142857142857143$$
