Talk:Ishango bone

message: This article claims that the bone is an example of Egyptian multiplication.  Could someone please point it out more explicitly to me? I don't see what's being multiplied, or what the result is.  And yes, I understand the concept of Egyptian multiplication. -Rwv37 18:10, 13 November 2005 (UTC)
thread_title:  Egyptian Multiplication? 

message: I believe the modern scholarly concensus dates this bone to approximately 6,500 BC.  I've changed the date.
: The reference used for this article states that it's 20,000 years old.  --Sean Brunnock 12:09, 31 March 2006 (UTC)

thread_title:  Ishango Bone 

message: I removed the following, from a sentence beginning with - The Ishango grouping may have been used to construct a number system "which is speculated to have spread north to Egypt and contributed to the development of mathematics".  We would definitely need a reliable source on this, this speculation seems highly unlikely to me.  This number system from 20,000 years ago is speculated to have spread to egypt, appearing over 10,000 years later in the egyptian mathematics?  Given the gap of many millennia, one would need serious evidence to make this claim.  --Xyzzyplugh 13:59, 26 November 2006 (UTC)
thread_title: Removed speculation

message: This article has been reassessed as part of the GA Sweeps project.  I have found a couple of problems with the article that make further work necessary to keep it at GA status.  Here is my review, my concerns are references and comprehensiveness.  Please contact me on my talk page if you have specific questions.  I will hold the article for a week and then reevaluate.

thread_title:  GA Reassessment 

message: Peter Rudman's "How Mathematics Happened: The First 50,000 Years", has a nice discussion on the validity of the speculations. The concept of the prime numbers for example cannot predate the division concept.  —Preceding unsigned comment added by 64.9.243.47 (talk) 04:09, 8 November 2010 (UTC)

thread_title:  Too many speculations 

message: Looking at the Royal Belgian Institute of Natural Sciences website there are two ishango bones. The first is the most well known with the 168 notches and a piece of quartz in one end. The second bone has an opening in one end with 90 major and minor notches on six sides.
