Whakaoti i te 3^{3}+3*5^2+2*3^2-4*(7^2*3-11^2+3)

$$3 ^ { 3 } + 3 \times 5 ^ { 2 } + 2 \times 3 ^ { 2 } - 4 \times ( 7 ^ { 2 } \times 3 - 11 ^ { 2 } + 3 )$$

Aromātai

Ngā Upane Otinga

Tātaihia te 3 mā te pū o 3, kia riro ko 27.

$$27+3\times 5^{2}+2\times 3^{2}-4\left(7^{2}\times 3-11^{2}+3\right)$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$27+3\times 25+2\times 3^{2}-4\left(7^{2}\times 3-11^{2}+3\right)$$

Whakareatia te 3 ki te 25, ka 75.

$$27+75+2\times 3^{2}-4\left(7^{2}\times 3-11^{2}+3\right)$$

Tāpirihia te 27 ki te 75, ka 102.

$$102+2\times 3^{2}-4\left(7^{2}\times 3-11^{2}+3\right)$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$102+2\times 9-4\left(7^{2}\times 3-11^{2}+3\right)$$

Whakareatia te 2 ki te 9, ka 18.

$$102+18-4\left(7^{2}\times 3-11^{2}+3\right)$$

Tāpirihia te 102 ki te 18, ka 120.

$$120-4\left(7^{2}\times 3-11^{2}+3\right)$$

Tātaihia te 7 mā te pū o 2, kia riro ko 49.

$$120-4\left(49\times 3-11^{2}+3\right)$$

Whakareatia te 49 ki te 3, ka 147.

$$120-4\left(147-11^{2}+3\right)$$

Tātaihia te 11 mā te pū o 2, kia riro ko 121.

$$120-4\left(147-121+3\right)$$

Tangohia te 121 i te 147, ka 26.

$$120-4\left(26+3\right)$$

Tāpirihia te 26 ki te 3, ka 29.

$$120-4\times 29$$

Whakareatia te 4 ki te 29, ka 116.

$$120-116$$

Tangohia te 116 i te 120, ka 4.
