Tātaihia te -7 mā te pū o 3, kia riro ko -343.

$$\frac{-343}{7^{2}}-\frac{\frac{2^{3}}{12^{0}}\left(-9\right)^{12}}{\left(-3\right)^{21}}$$

Tātaihia te 7 mā te pū o 2, kia riro ko 49.

$$\frac{-343}{49}-\frac{\frac{2^{3}}{12^{0}}\left(-9\right)^{12}}{\left(-3\right)^{21}}$$

Whakawehea te -343 ki te 49, kia riro ko -7.

$$-7-\frac{\frac{2^{3}}{12^{0}}\left(-9\right)^{12}}{\left(-3\right)^{21}}$$

Tātaihia te 2 mā te pū o 3, kia riro ko 8.

$$-7-\frac{\frac{8}{12^{0}}\left(-9\right)^{12}}{\left(-3\right)^{21}}$$

Tātaihia te 12 mā te pū o 0, kia riro ko 1.

$$-7-\frac{\frac{8}{1}\left(-9\right)^{12}}{\left(-3\right)^{21}}$$

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$-7-\frac{8\left(-9\right)^{12}}{\left(-3\right)^{21}}$$

Tātaihia te -9 mā te pū o 12, kia riro ko 282429536481.

$$-7-\frac{8\times 282429536481}{\left(-3\right)^{21}}$$

Whakareatia te 8 ki te 282429536481, ka 2259436291848.

$$-7-\frac{2259436291848}{\left(-3\right)^{21}}$$

Tātaihia te -3 mā te pū o 21, kia riro ko -10460353203.

$$-7-\frac{2259436291848}{-10460353203}$$

Whakawehea te 2259436291848 ki te -10460353203, kia riro ko -216.

$$-7-\left(-216\right)$$

Ko te tauaro o -216 ko 216.

$$-7+216$$

Tāpirihia te -7 ki te 216, ka 209.

$$209$$
