Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 8 me te 7 kia riro ai te 15.

$$2\times 10^{15}\times 2\times 5$$

Tātaihia te 10 mā te pū o 15, kia riro ko 1000000000000000.

$$2\times 1000000000000000\times 2\times 5$$

Whakareatia te 2 ki te 1000000000000000, ka 2000000000000000.

$$2000000000000000\times 2\times 5$$

Whakareatia te 2000000000000000 ki te 2, ka 4000000000000000.

$$4000000000000000\times 5$$

Whakareatia te 4000000000000000 ki te 5, ka 20000000000000000.
