Why did positional notation spread quickly in western Europe?

  1. It was cheaper to print
  2. It made sums much simpler
  3. It looked like Latin
  4. It needed no digits
Show answer and solution

Correct answer: B. It made sums much simpler

1. Positional notation makes arithmetic computations much simpler than older systems. 2. This led to its rapid spread when it was introduced in western Europe. 3. Printing cost, Latin looks and having no digits are not the reasons given. _Source: Wikipedia, Positional notation, Lead section_
