Do you add anything to damage rolls?

How does damage roll work?
A damage roll determines how much damage you deal with an attack. Damage rolls vary widely with the different powers and weapons that can be involved, but the basic formula is often the same. If you’re using a weapon for the attack, the damage is often some multiple of your weapon damage dice.
What do you add to damage rolls in DND?
When attacking with a weapon, you add your ability modifier—the same modifier used for the Attack roll—to the damage. A spell tells you which dice to roll for damage and whether to add any modifiers.

Do you add your ability modifier to your damage roll?
