Solve (24-32-8)-(15-27-9)+(20+4-15)

$$( 24 - 32 - 8 ) - ( 15 - 27 - 9 ) + ( 20 + 4 - 15 )$$

Evaluate

$$14$$

Solution Steps

Subtract 32 from 24 to get -8.

$$-8-8-\left(15-27-9\right)+20+4-15$$

Subtract 8 from -8 to get -16.

$$-16-\left(15-27-9\right)+20+4-15$$

Subtract 27 from 15 to get -12.

$$-16-\left(-12-9\right)+20+4-15$$

Subtract 9 from -12 to get -21.

$$-16-\left(-21\right)+20+4-15$$

The opposite of -21 is 21.

$$-16+21+20+4-15$$

Add -16 and 21 to get 5.

$$5+20+4-15$$

Add 5 and 20 to get 25.

$$25+4-15$$

Add 25 and 4 to get 29.

$$29-15$$

Subtract 15 from 29 to get 14.

$$14$$

Factor

$$2\times 7$$
