|-5.8+5.4-\frac{1}{2}|
Tangohia te 2.1 i te -3.7, ka -5.8.
|-0.4-\frac{1}{2}|
Tāpirihia te -5.8 ki te 5.4, ka -0.4.
|-\frac{2}{5}-\frac{1}{2}|
Me tahuri ki tau ā-ira -0.4 ki te hautau -\frac{4}{10}. Whakahekea te hautanga -\frac{4}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
|-\frac{4}{10}-\frac{5}{10}|
Ko te maha noa iti rawa atu o 5 me 2 ko 10. Me tahuri -\frac{2}{5} me \frac{1}{2} ki te hautau me te tautūnga 10.
|\frac{-4-5}{10}|
Tā te mea he rite te tauraro o -\frac{4}{10} me \frac{5}{10}, me tango rāua mā te tango i ō raua taurunga.
|-\frac{9}{10}|
Tangohia te 5 i te -4, ka -9.
\frac{9}{10}
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{9}{10} ko \frac{9}{10}.
