Solve 5-left(7-2-left(1-9right)-3+12right)+4

$$5- \left( 7-2- \left( 1-9 \right) -3+12 \right) +4$$

Evaluate

$$-13$$

Solution Steps

Subtract 2 from 7 to get 5.

$$5-\left(5-\left(1-9\right)-3+12\right)+4$$

Subtract 9 from 1 to get -8.

$$5-\left(5-\left(-8\right)-3+12\right)+4$$

The opposite of -8 is 8.

$$5-\left(5+8-3+12\right)+4$$

Add 5 and 8 to get 13.

$$5-\left(13-3+12\right)+4$$

Subtract 3 from 13 to get 10.

$$5-\left(10+12\right)+4$$

Add 10 and 12 to get 22.

$$5-22+4$$

Subtract 22 from 5 to get -17.

$$-17+4$$

Add -17 and 4 to get -13.

$$-13$$

Factor
