Solve 12-2(-3-7(5-2*3^2))

$$12 - 2 ( - 3 - 7 ( 5 - 2 \cdot 3 ^ { 2 } ) )$$

Evaluate

$$-164$$

Solution Steps

Calculate 3 to the power of 2 and get 9.

$$12-2\left(-3-7\left(5-2\times 9\right)\right)$$

Multiply 2 and 9 to get 18.

$$12-2\left(-3-7\left(5-18\right)\right)$$

Subtract 18 from 5 to get -13.

$$12-2\left(-3-7\left(-13\right)\right)$$

Multiply 7 and -13 to get -91.

$$12-2\left(-3-\left(-91\right)\right)$$

The opposite of -91 is 91.

$$12-2\left(-3+91\right)$$

Add -3 and 91 to get 88.

$$12-2\times 88$$

Multiply 2 and 88 to get 176.

$$12-176$$

Subtract 176 from 12 to get -164.

$$-164$$
