Dear friends,

If I write:

In[1]:= Subscript[a, 11];
In[2]:= Subscript[a, 12];

Q1: How I can Clear or Remove the previous definitions?. 
Q2: Is it posible to clear at the same time all definitions with pattern:
Subscript[a, i] (* i=1,2,..*)

I wish to avoid using Notation Package 

I have tested:

In[3]: Clear[Subscript[a, 11]]
Message: Clear:: "ssym": a_11 is not a symbol or a string

In[4]: Clear["\!\(a\_11\)"]

But they don`t work
