Add a second email in gmail?

I'm at LapTop and do not know how to add a second email in gmail.

It should work here.

I have already created one on my phone, but it is not displayed on laptop (logically, are two different systems) and I would like to be able to view my laptop now

Unfortunately, I can't help you, I do not have a cell phone.

Me too no more, so I want to add the email now on the laptop!
