  • Digits from zero to nine are rendered by specific words: sero (or dim) [0], un [1], dau / dwy (masculine/feminine) [2], tri / tair (masculine/feminine) [3], pedwar / pedair (masculine/feminine) [4], pump (or pum when directly followed by a noun) [5], chwech (or chwe when directly followed by a noun) [6], saith [7], wyth [8], and naw [9].
  • The tens in the decimal system are formed by prefixing the word for ten (deg) with its multiplier digit (separated with a space or not): deg [10], dauddeg [20], trideg [30], pedwardeg [40], pumdeg [50], chwedeg [60], saithdeg [70], wythdeg [80], and nawdeg [90].
  • Teens are formed by starting with the word for ten (deg) prefixed by its multiplier (one), followed by the unit, separated with a space: undeg un [11], undeg dau [12], undeg tri [13], undeg pedwar [14], undeg pump [15], undeg chwech [16], undeg saith [17], undeg wyth [18], and undeg naw [19].
  • Compound numbers are formed the same way, starting with the ten, followed by the unit digit (e.g.: dauddeg pump [25], chwedeg pedwar [64]).
  • Hundreds are formed by stating the multiplier digit before the word for hundred (cant, gant or chant), except for one hundred: cant [100], dau gant [200], tri chant [300], pedwar cant [400], pum cant [500], chwe chant [600], saith cant [700], wyth cant [800], and naw cant [900].
  • When compound with numbers from one to ten, hundreds are linked with the particle ac or a (e.g.: cant ac un [101], cant a dau [102], cant a deg [110]), while no particule is needed between the hundred and upper numbers (e.g.: cant dauddeg [120]).
  • Thousands are formed by stating the multiplier digit before the word for thousand (mil), except for one thousand: mil [1,000], dau vil [2,000], tri mil [3,000], pedwar mil [4,000], pump mil [5,000], chwech mil [6,000], saith mil [7,000], wyth mil [8,000], and naw mil [9,000].
  • The word for million is miliwn (plural: miliynau), and the word for billion (109) is biliwn (plural: biliynau).
