Solve 1-4[1-7(2-3^3)-12]+25

$$1 - 4 [ 1 - 7 ( 2 - 3 ^ { 3 } ) - 12 ] + 25$$

Evaluate

$$-630$$

Solution Steps

Calculate 3 to the power of 3 and get 27.

$$1-4\left(1-7\left(2-27\right)-12\right)+25$$

Subtract 27 from 2 to get -25.

$$1-4\left(1-7\left(-25\right)-12\right)+25$$

Multiply 7 and -25 to get -175.

$$1-4\left(1-\left(-175\right)-12\right)+25$$

The opposite of -175 is 175.

$$1-4\left(1+175-12\right)+25$$

Add 1 and 175 to get 176.

$$1-4\left(176-12\right)+25$$

Subtract 12 from 176 to get 164.

$$1-4\times 164+25$$

Multiply 4 and 164 to get 656.

$$1-656+25$$

Subtract 656 from 1 to get -655.

$$-655+25$$

Add -655 and 25 to get -630.

$$-630$$

Factor

$$-630$$
