How do I know my Ethereum address?

Excuse me, I'm a bit new to the world of cryptocurrencies and I'm having a bit of trouble. Could you please explain to me how I can find out what my Ethereum address is? I've heard that it's essential for transactions and I want to make sure I'm doing everything correctly. Is there a specific way to locate it in my wallet or do I need to use a special tool? I'd really appreciate any guidance you can provide.
