Extract

There is probably no other item of the arithmetic syllabus which is confronted by such a diversity of earnestly supported method as is the case with the multiplication of decimals.

The problems which form the basis of this investigation are :

  1. (a) What are the special advantages and disadvantages which bring about the adoption or rejection of these methods?

  2. (b) What is the extent of these advantages and disadvantages?

  3. (c) And finally a consideration of the methods of overcoming the disadvantages.
