It has been suggested that History of writing ancient numbers be merged into History of writing numbers. 

That is backwards.  I created History of writing ancient numbers from History of writing numbers because "History of writing numbers" was too broad a title and overlapped the subject matter of "History of numerals" and "Numeral system]]. Leave "History of writing ancient numbers" alone.  I will erase and redirect the other page.   

I hope I got it right this time.  I accidently erased then reverted History of writing ancient numbers.  I reduced this page to a stub (to be redirected later) because the proposed merger was effectedly done a week ago.  Sorry for the confusion.
