Ngā Upane Otinga

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te -1 me te 5 kia riro ai te -5.

$$3\times 8^{-5}-4^{2}$$

Tātaihia te 8 mā te pū o -5, kia riro ko \frac{1}{32768}.

$$3\times \frac{1}{32768}-4^{2}$$

Whakareatia te 3 ki te \frac{1}{32768}, ka \frac{3}{32768}.

$$\frac{3}{32768}-4^{2}$$

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$\frac{3}{32768}-16$$

Tangohia te 16 i te \frac{3}{32768}, ka -\frac{524285}{32768}.

$$-\frac{524285}{32768}$$

Tauwehe

$$-\frac{524285}{32768} = -15\frac{32765}{32768} = -15.999908447265625$$
