Whakareatia te 10 ki te 2.5, ka 25.

$$25+\frac{1}{2}\left(-9.8\right)\times 2.5^{2}$$

Me tahuri ki tau ā-ira -9.8 ki te hautau -\frac{98}{10}. Whakahekea te hautanga -\frac{98}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$25+\frac{1}{2}\left(-\frac{49}{5}\right)\times 2.5^{2}$$

Me whakarea te \frac{1}{2} ki te -\frac{49}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$25+\frac{1\left(-49\right)}{2\times 5}\times 2.5^{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\left(-49\right)}{2\times 5}.

$$25+\frac{-49}{10}\times 2.5^{2}$$

Ka taea te hautanga \frac{-49}{10} te tuhi anō ko -\frac{49}{10} mā te tango i te tohu tōraro.

$$25-\frac{49}{10}\times 2.5^{2}$$

Tātaihia te 2.5 mā te pū o 2, kia riro ko 6.25.

$$25-\frac{49}{10}\times 6.25$$

Me tahuri ki tau ā-ira 6.25 ki te hautau \frac{625}{100}. Whakahekea te hautanga \frac{625}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$25-\frac{49}{10}\times \frac{25}{4}$$

Me whakarea te -\frac{49}{10} ki te \frac{25}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$25+\frac{-49\times 25}{10\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{-49\times 25}{10\times 4}.

$$25+\frac{-1225}{40}$$

Whakahekea te hautanga \frac{-1225}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$25-\frac{245}{8}$$

Me tahuri te 25 ki te hautau \frac{200}{8}.

$$\frac{200}{8}-\frac{245}{8}$$

Tā te mea he rite te tauraro o \frac{200}{8} me \frac{245}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{200-245}{8}$$

Tangohia te 245 i te 200, ka -45.

$$-\frac{45}{8}$$
