Me tahuri ki tau ā-ira -8.4 ki te hautau -\frac{84}{10}. Whakahekea te hautanga -\frac{84}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$16.09-\left(-\frac{42}{5}\left(-\frac{7}{12}\right)\right)-\left(-3.7\right)^{2}$$

Me whakarea te -\frac{42}{5} ki te -\frac{7}{12} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$16.09-\frac{-42\left(-7\right)}{5\times 12}-\left(-3.7\right)^{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{-42\left(-7\right)}{5\times 12}.

$$16.09-\frac{294}{60}-\left(-3.7\right)^{2}$$

Whakahekea te hautanga \frac{294}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$16.09-\frac{49}{10}-\left(-3.7\right)^{2}$$

Me tahuri ki tau ā-ira 16.09 ki te hautau \frac{1609}{100}.

$$\frac{1609}{100}-\frac{49}{10}-\left(-3.7\right)^{2}$$

Ko te maha noa iti rawa atu o 100 me 10 ko 100. Me tahuri \frac{1609}{100} me \frac{49}{10} ki te hautau me te tautūnga 100.

$$\frac{1609}{100}-\frac{490}{100}-\left(-3.7\right)^{2}$$

Tā te mea he rite te tauraro o \frac{1609}{100} me \frac{490}{100}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1609-490}{100}-\left(-3.7\right)^{2}$$

Tangohia te 490 i te 1609, ka 1119.

$$\frac{1119}{100}-\left(-3.7\right)^{2}$$

Tātaihia te -3.7 mā te pū o 2, kia riro ko 13.69.

$$\frac{1119}{100}-13.69$$

Me tahuri ki tau ā-ira 13.69 ki te hautau \frac{1369}{100}.

$$\frac{1119}{100}-\frac{1369}{100}$$

Tā te mea he rite te tauraro o \frac{1119}{100} me \frac{1369}{100}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1119-1369}{100}$$

Tangohia te 1369 i te 1119, ka -250.

$$\frac{-250}{100}$$

Whakahekea te hautanga \frac{-250}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 50.
