How do you say a location in Japanese?

Question:

How do you say where you're located? I.E. how do you say:

I am at the bank.
I am in class.

Answer:

You use iru to say where you are. It's polite version is imasu.

>I am at the bank.
銀行にいます ginkou ni imasu

>I am in class.
教室にいます kyoshitsu ni imasu

You can add "watashi wa" at the beginning to say "I am". But it's often omitted.
