Whakaoti i te |-21/2|-(-2.5)+1-|1-21/2|

$$| - 2 \frac { 1 } { 2 } | - ( - 2.5 ) + 1 - | 1 - 2 \frac { 1 } { 2 } |$$

Aromātai

$$4.5$$

Ngā Upane Otinga

Whakareatia te 2 ki te 2, ka 4.

$$|-\frac{4+1}{2}|-\left(-2.5\right)+1-|1-\frac{2\times 2+1}{2}|$$

Tāpirihia te 4 ki te 1, ka 5.

$$|-\frac{5}{2}|-\left(-2.5\right)+1-|1-\frac{2\times 2+1}{2}|$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o -\frac{5}{2} ko \frac{5}{2}.

$$\frac{5}{2}-\left(-2.5\right)+1-|1-\frac{2\times 2+1}{2}|$$

Ko te tauaro o -2.5 ko 2.5.

$$\frac{5}{2}+2.5+1-|1-\frac{2\times 2+1}{2}|$$

Me tahuri ki tau ā-ira 2.5 ki te hautau \frac{25}{10}. Whakahekea te hautanga \frac{25}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{5}{2}+\frac{5}{2}+1-|1-\frac{2\times 2+1}{2}|$$

Tā te mea he rite te tauraro o \frac{5}{2} me \frac{5}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{5+5}{2}+1-|1-\frac{2\times 2+1}{2}|$$

Tāpirihia te 5 ki te 5, ka 10.

$$\frac{10}{2}+1-|1-\frac{2\times 2+1}{2}|$$

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

$$5+1-|1-\frac{2\times 2+1}{2}|$$

Tāpirihia te 5 ki te 1, ka 6.

$$6-|1-\frac{2\times 2+1}{2}|$$

Whakareatia te 2 ki te 2, ka 4.

$$6-|1-\frac{4+1}{2}|$$

Tāpirihia te 4 ki te 1, ka 5.

$$6-|1-\frac{5}{2}|$$

Me tahuri te 1 ki te hautau \frac{2}{2}.

$$6-|\frac{2}{2}-\frac{5}{2}|$$

Tā te mea he rite te tauraro o \frac{2}{2} me \frac{5}{2}, me tango rāua mā te tango i ō raua taurunga.

$$6-|\frac{2-5}{2}|$$

Tangohia te 5 i te 2, ka -3.

$$6-|-\frac{3}{2}|$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o -\frac{3}{2} ko \frac{3}{2}.

$$6-\frac{3}{2}$$

Me tahuri te 6 ki te hautau \frac{12}{2}.

$$\frac{12}{2}-\frac{3}{2}$$

Tā te mea he rite te tauraro o \frac{12}{2} me \frac{3}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{12-3}{2}$$

Tangohia te 3 i te 12, ka 9.

$$\frac{9}{2}$$

Tauwehe

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4.5$$
