Solve -4[5(-3)+12-4)+2(13-7)

$$- 4 [ 5 ( - 3 ) + 12 - 4 ) + 2 ( 13 - 7 )$$

Evaluate

$$40$$

Solution Steps

Multiply 5 and -3 to get -15.

$$-4\left(-15+12-4\right)+2\left(13-7\right)$$

Add -15 and 12 to get -3.

$$-4\left(-3-4\right)+2\left(13-7\right)$$

Subtract 4 from -3 to get -7.

$$-4\left(-7\right)+2\left(13-7\right)$$

Multiply -4 and -7 to get 28.

$$28+2\left(13-7\right)$$

Subtract 7 from 13 to get 6.

$$28+2\times 6$$

Multiply 2 and 6 to get 12.

$$28+12$$

Add 28 and 12 to get 40.

$$40$$

Factor

$$2^{3}\times 5$$
