Whakaoti i te C=3^2-5*(3-7)+(7^2-2*24)

$$C = 3 ^ { 2 } - 5 \times ( 3 - 7 ) + ( 7 ^ { 2 } - 2 \times 24 )$$

Whakaoti mō C

$$C=30$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$C=9-5\left(3-7\right)+7^{2}-2\times 24$$

Tangohia te 7 i te 3, ka -4.

$$C=9-5\left(-4\right)+7^{2}-2\times 24$$

Whakareatia te 5 ki te -4, ka -20.

$$C=9-\left(-20\right)+7^{2}-2\times 24$$

Ko te tauaro o -20 ko 20.

$$C=9+20+7^{2}-2\times 24$$

Tāpirihia te 9 ki te 20, ka 29.

$$C=29+7^{2}-2\times 24$$

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

$$C=29+49-2\times 24$$

Whakareatia te 2 ki te 24, ka 48.

$$C=29+49-48$$

Tangohia te 48 i te 49, ka 1.

$$C=29+1$$

Tāpirihia te 29 ki te 1, ka 30.

$$C=30$$

Tautapa C

$$C≔30$$
