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

$$3-14\times 4+3.14\times 2\times 2\times 4=62.8$$

Whakareatia te 14 ki te 4, ka 56.

$$3-56+3.14\times 2\times 2\times 4=62.8$$

Tangohia te 56 i te 3, ka -53.

$$-53+3.14\times 2\times 2\times 4=62.8$$

Whakareatia te 3.14 ki te 2, ka 6.28.

$$-53+6.28\times 2\times 4=62.8$$

Whakareatia te 6.28 ki te 2, ka 12.56.

$$-53+12.56\times 4=62.8$$

Whakareatia te 12.56 ki te 4, ka 50.24.

$$-53+50.24=62.8$$

Tāpirihia te -53 ki te 50.24, ka -2.76.

$$-2.76=62.8$$

Whakatauritea te -2.76 me te 62.8.
