  • 20:2420:24, 27 February 2021 diff hist +90 MultiplicationThe reversion is wrong. Euc. div. follows from the division def, the principle nevertheless holds; and Euclid's initial def (Book VII, Def 15) does not see the modern binary framework—and neither does he for the addition for that matter. Second, the universally used expression for the euc. div is a=b×q+r which explicitizes the groupings (which is "b multiplied by q" or "q times (the number) b"). Furthermore: multiplicand × multiplier. Note: simple.wikipedia.org has got it right. Tag: Reverted
  • 20:0320:03, 27 February 2021 diff hist +61 MultiplicationThe reversion is somewhat wrong.The euclidean division might follow from the division definition, the principle nevertheless holds. First, the initial definition is very different from current ones (see Euclid's Elements, Book VII, Def. 15) and cannot be explicitly followed in that context since he does not see the modern binary framework — and neither does he for the addition, for that matter.

  • 20:1120:11, 25 February 2021 diff hist +4 MultiplicationSame as last edit, order was wrong (as common as it is, it remains quite a stupid error: you just have to understand the euclidean division a=b×q+r). Tags: Reverted Mobile edit Mobile web edit
  • 20:0420:04, 25 February 2021 diff hist 0 MultiplicationThe definition is inverted ! 2*3 is three times the value two. This is a very common error, and disheartening to see on Wikipedia! The proof comes from euclidean division. a=b×q+r, where, clearly, q groups of b elements are taken, hence b+b+b+…, q times. Tags: Reverted Mobile edit Mobile web edit
