Well, it will be like: "i" sound in portuguese. I mean, "eee". But if you mean "é" it's diferent. The first one is a conjugation and the second is a verb (to be). So, the pronunciation is diferent. However, the correct pronunciation to "e" as "and" is "ee" in english. Just like tree, free, see.

The "e" as in And is like as letter "A"(Ei) but only E sound.

eeeee is right to speak, more natural. "e" almost nobody speaks...only reading a text, strong formal. é - open, is a verb to be.

Hello, Ansel! It's a little hard to explain how to say something in another language, but I will try to use english to help you. The "e" has the same pronunciation of "hey" and "may" in english. The "a" of "may" has the same sound of "e". If you have anothers doubts, I can try to explain to you, OK?
