Solution Steps

Subtract 7.2 from -3.5 to get -10.7.

$$-10.7-4.1+15.3+9.1-7.7-1.3+13.7+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Subtract 4.1 from -10.7 to get -14.8.

$$-14.8+15.3+9.1-7.7-1.3+13.7+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Add -14.8 and 15.3 to get 0.5.

$$0.5+9.1-7.7-1.3+13.7+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Add 0.5 and 9.1 to get 9.6.

$$9.6-7.7-1.3+13.7+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Subtract 7.7 from 9.6 to get 1.9.

$$1.9-1.3+13.7+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Subtract 1.3 from 1.9 to get 0.6.

$$0.6+13.7+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Add 0.6 and 13.7 to get 14.3.

$$14.3+6.7-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Add 14.3 and 6.7 to get 21.

$$21-12.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Subtract 12.5 from 21 to get 8.5.

$$8.5+7.4+2.6+1.9-4.3-5.9-3.2$$

Add 8.5 and 7.4 to get 15.9.

$$15.9+2.6+1.9-4.3-5.9-3.2$$

Add 15.9 and 2.6 to get 18.5.

$$18.5+1.9-4.3-5.9-3.2$$

Add 18.5 and 1.9 to get 20.4.

$$20.4-4.3-5.9-3.2$$

Subtract 4.3 from 20.4 to get 16.1.

$$16.1-5.9-3.2$$

Subtract 5.9 from 16.1 to get 10.2.

$$10.2-3.2$$

Subtract 3.2 from 10.2 to get 7.

$$7$$
