Solve -{12-3-[-5*(19--7)+8]--9*7}+1=

$$- \{ 12 - 3 - [ - 5 \cdot ( 19 - - 7 ) + 8 ] - - 9 \cdot 7 \} + 1 =$$

Evaluate

$$-193$$

Solution Steps

Subtract 3 from 12 to get 9.

$$-\left(9-\left(-5\left(19-\left(-7\right)\right)+8\right)-\left(-9\times 7\right)\right)+1$$

The opposite of -7 is 7.

$$-\left(9-\left(-5\left(19+7\right)+8\right)-\left(-9\times 7\right)\right)+1$$

Add 19 and 7 to get 26.

$$-\left(9-\left(-5\times 26+8\right)-\left(-9\times 7\right)\right)+1$$

Multiply -5 and 26 to get -130.

$$-\left(9-\left(-130+8\right)-\left(-9\times 7\right)\right)+1$$

Add -130 and 8 to get -122.

$$-\left(9-\left(-122\right)-\left(-9\times 7\right)\right)+1$$

The opposite of -122 is 122.

$$-\left(9+122-\left(-9\times 7\right)\right)+1$$

Add 9 and 122 to get 131.

$$-\left(131-\left(-9\times 7\right)\right)+1$$

Multiply -9 and 7 to get -63.

$$-\left(131-\left(-63\right)\right)+1$$

The opposite of -63 is 63.

$$-\left(131+63\right)+1$$

Add 131 and 63 to get 194.

$$-194+1$$

Add -194 and 1 to get -193.

$$-193$$

Factor

$$-193$$
