It was the Q1 parts of your code that really tipped me off.  I suppose 
you could be planning on a future Q1 class, but it did make it look like 
you where taking a course over the summer.

BTW, another way to improve you code is to watch the big cascades of 
if-else statements.  For example this:

       if (btn == ".") {strng1 += btn;}
       else if (btn == "0") {strng1 += btn;}
       else if (btn == "1") {strng1 += btn;}
       else if (btn == "2") {strng1 += btn;}
       else if (btn == "3") {strng1 += btn;}
       else if (btn == "4") {strng1 += btn;}
       else if (btn == "5") {strng1 += btn;}
       else if (btn == "6") {strng1 += btn;}
       else if (btn == "7") {strng1 += btn;}
       else if (btn == "8") {strng1 += btn;}
       else if (btn == "9") {strng1 += btn;}

could all just be

   strng1 += btn;

because you don't do anything different for the different cases. 
Copy-paste statement like this should be avoid, because it creates 
relatively low value redundancy.  Try to combine common cases into one 
block.  It's easier to go back and modify later.
