Whakaoti i te 5(4-5)^2+3(5-1)-2(1+2)^2(2)+2(3)(4)

$$5 ( 4 - 5 ) ^ { 2 } + 3 ( 5 - 1 ) - 2 ( 1 + 2 ) ^ { 2 } ( 2 ) + 2 ( 3 ) ( 4 )$$

Aromātai

$$5$$

Ngā Upane Otinga

Tangohia te 5 i te 4, ka -1.

$$5\left(-1\right)^{2}+3\left(5-1\right)-2\left(1+2\right)^{2}\times 2+2\times 3\times 4$$

Tātaihia te -1 mā te pū o 2, kia riro ko 1.

$$5\times 1+3\left(5-1\right)-2\left(1+2\right)^{2}\times 2+2\times 3\times 4$$

Whakareatia te 5 ki te 1, ka 5.

$$5+3\left(5-1\right)-2\left(1+2\right)^{2}\times 2+2\times 3\times 4$$

Tangohia te 1 i te 5, ka 4.

$$5+3\times 4-2\left(1+2\right)^{2}\times 2+2\times 3\times 4$$

Whakareatia te 3 ki te 4, ka 12.

$$5+12-2\left(1+2\right)^{2}\times 2+2\times 3\times 4$$

Tāpirihia te 5 ki te 12, ka 17.

$$17-2\left(1+2\right)^{2}\times 2+2\times 3\times 4$$

Tāpirihia te 1 ki te 2, ka 3.

$$17-2\times 3^{2}\times 2+2\times 3\times 4$$

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

$$17-2\times 9\times 2+2\times 3\times 4$$

Whakareatia te 2 ki te 9, ka 18.

$$17-18\times 2+2\times 3\times 4$$

Whakareatia te 18 ki te 2, ka 36.

$$17-36+2\times 3\times 4$$

Tangohia te 36 i te 17, ka -19.

$$-19+2\times 3\times 4$$

Whakareatia te 2 ki te 3, ka 6.

$$-19+6\times 4$$

Whakareatia te 6 ki te 4, ka 24.

$$-19+24$$

Tāpirihia te -19 ki te 24, ka 5.
