Jack, 

      Very good paper about early Indian mathematics and the 
   various algebraic ideas it contained.  Incidentally, I was 
   not seeing any of your equations and I was about to start 
   writing comments like "where are the equations?"  But
   just in case, I tried opening the file with MS Word,
   rather than Google Docs, and the equations came through
   fine there.  This is just for your information in case 
   you ever want to submit a paper containing elements like 
   equations for another class.  It would probably make sense 
   to mention this to whoever is going to read the paper
   so that the effects of what I guess is a compatibility
   issue between MS Word and Google Sheets can be minimized 
   (if not avoided completely) for your reader.

   One comment about your discussion of the Sulba-sutras:
   another very interesting aspect is the use of numerical
   relationships between different lengths of segments of
   the altars that come down to integer Pythagorean triples
   (a,b,c) with c^2 = a^2 + b^2, such as (3,4,5), (5,12,13), 
   (7,24,25), and so forth.  Many of the common "smaller" 
   triples come into the designs in various ways.  Did your 
   sources mention that aspect?   

   The dating of the Sulba-sutras is not firmly determined,
   as you indicate.  But the fact that such similar ideas come
   in both Old Babylonian mathematics and in Greek mathematics
   has prompted some historians to suggest that there might
   have been trade and other contacts by which these ideas
   were spread between these different areas.  In other words,
   the fact that similar ideas are found in different places
   could come from the fact that people were communicating
   mathematical ideas to each other.
