Talk:Rod calculus

Oppose --Because rod calculus is a very lengthy topic, a full discussion need to to include not only addition, subtraction, mulitplicatio, and division, but also should include the extraction of square roots, cubic roots, solving high order equation with counting rods etc, the thaat would make it too lengthy for an article. Further more, Rod calculus was the equivalent of software, while counting rod was the equivalent of hardware, there is no reason to merge "microsoft" with Dell, or IBM, they are different entities. ---Gisling (talk) 01:14, 12 April 2010 (UTC).

Multiplication

I recently compared the multiplication algorithm currently shown with explanations in the Google preview of Fleeting Footsteps, and they don't seem to match very well. FF shows a single result accumulated after the multiplication of each digit of each number, as opposed to technique currently given where an intermediate result is accumulated from the product of a single digit of the multiplicand times the entire multiplier. Is there a reference for the technique shown? Also, application of the carry in the example seems bizarre. A carry in the second intermediate result is applied to the first intermediate result. It seems the two intermediate results should be 2280 and 608. —Soniakeys (talk) 18:51, 1 June 2011 (UTC)

Square root algorithm

The English description of the square root algorithm is wrong. Following the Chinese instruction yields a process that is very similar to that found here: http://en.wikipedia.org/wiki/Methods_of_computing_square_roots#Decimal_.28base_10.29. —TKCuse (talk) 05:10, 26 July 2014 (UTC)

GIF animations of examples

Examples in GIF animations:

• should have numbered steps, or
• should be replaced with slideshow controlled by user (if possible), or
• should be merged into one image with numbered steps,

otherwise they are hard to follow.
