Numeracy

Place-value is an important and sometimes difficult concept for pupils to grasp. Esperanto, being a regular language, has a consistent nd easily explained number system.

  • unu = 1
  • du = 2
  • dek = 10
  • dek unu = 11
  • dudek unu = 21
  • cent = 100
  • ducent dudek unu = 221
  • mil = 1000
  • mil ducent dudek unu = 1, 221

Fractions are denoted by a suffix -on-, e.g:

  • 2 = du, 1/2 = duono
  • 4 = kvar, 1/4 = kvarono
