Tohaina
Kua tāruatia ki te papatopenga
15-6\times 1=-1+3-\left(1+2\right)+10
Whakareatia te 15 ki te 1, ka 15.
15-6=-1+3-\left(1+2\right)+10
Whakareatia te 6 ki te 1, ka 6.
9=-1+3-\left(1+2\right)+10
Tangohia te 6 i te 15, ka 9.
9=2-\left(1+2\right)+10
Tāpirihia te -1 ki te 3, ka 2.
9=2-3+10
Tāpirihia te 1 ki te 2, ka 3.
9=-1+10
Tangohia te 3 i te 2, ka -1.
9=9
Tāpirihia te -1 ki te 10, ka 9.
\text{true}
Whakatauritea te 9 me te 9.
