If you multiply me by any other number, the result is always the same, regardless of what number you chose. Yet, if you add me to a number, my value vanishes and leaves the other number completely unchanged. What am I?
Zero
Multiplying any number by zero yields zero. Adding zero to any number leaves that number unchanged (the additive identity).
