$$- 13 + ( - 5 - 1 - 2 - ( - 3 - 1 ) + ( - 7 ) 1 - ( - 6 + 1 - 3 ) ) - 5$$

Evaluate

$$-21$$

Solution Steps

Subtract 1 from -5 to get -6.

$$-13+-6-2-\left(-3-1\right)-7-\left(-6+1-3\right)-5$$

Subtract 2 from -6 to get -8.

$$-13+-8-\left(-3-1\right)-7-\left(-6+1-3\right)-5$$

Subtract 1 from -3 to get -4.

$$-13+-8-\left(-4\right)-7-\left(-6+1-3\right)-5$$

The opposite of -4 is 4.

$$-13+-8+4-7-\left(-6+1-3\right)-5$$

Add -8 and 4 to get -4.

$$-13+-4-7-\left(-6+1-3\right)-5$$

Subtract 7 from -4 to get -11.

$$-13+-11-\left(-6+1-3\right)-5$$

Add -6 and 1 to get -5.

$$-13+-11-\left(-5-3\right)-5$$

Subtract 3 from -5 to get -8.

$$-13+-11-\left(-8\right)-5$$

The opposite of -8 is 8.

$$-13-11+8-5$$
