Solve (3-8)+(-5-2)-(-9+1)-(7-5)=

$$( 3 - 8 ) + ( - 5 - 2 ) - ( - 9 + 1 ) - ( 7 - 5 ) =$$

Evaluate

$$-6$$

Solution Steps

Subtract 8 from 3 to get -5.

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

Subtract 5 from -5 to get -10.

$$-10-2-\left(-9+1\right)-\left(7-5\right)$$

Subtract 2 from -10 to get -12.

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

Add -9 and 1 to get -8.

$$-12-\left(-8\right)-\left(7-5\right)$$

The opposite of -8 is 8.

$$-12+8-\left(7-5\right)$$

Add -12 and 8 to get -4.

$$-4-\left(7-5\right)$$

Subtract 5 from 7 to get 2.

$$-4-2$$

Subtract 2 from -4 to get -6.

$$-6$$
