Kua tāruatia ki te papatopenga
15-\lceil 7-\frac{8+1}{4}\rceil
Whakareatia te 2 ki te 4, ka 8.
15-\lceil 7-\frac{9}{4}\rceil
Tāpirihia te 8 ki te 1, ka 9.
15-\lceil \frac{28}{4}-\frac{9}{4}\rceil
Me tahuri te 7 ki te hautau \frac{28}{4}.
15-\lceil \frac{28-9}{4}\rceil
Tā te mea he rite te tauraro o \frac{28}{4} me \frac{9}{4}, me tango rāua mā te tango i ō raua taurunga.
15-\lceil \frac{19}{4}\rceil
Tangohia te 9 i te 28, ka 19.
15-\lceil 4+\frac{3}{4}\rceil
Ka ritua te 19 mā te 4 ka puta ko 4 me te toenga 3. Tuhia anō te \frac{19}{4} hei 4+\frac{3}{4}.
15-5
Ko te tuanui o tētahi tau tūturu a ko te tau tōpū tino iti rawa he nui ake, he ōrite rānei ki a. Ko te tuanui o 4+\frac{3}{4} ko 5.
10
Tangohia te 5 i te 15, ka 10.
