Northern Sami uses a decimal numeral system. Cardinal numbers inflect like adjectives, but have no attributive form. Instead, the numeral matches the noun it modifies in case and number. All numerals except for "okta" (1) use the nominative singular form also for the accusative singular (both are in the same consonant grade). For "čieža" (7), "gávcci" (8), "ovcci" (9), "logi" (10) and "čuođi" (100), the genitive singular form is used also for the nominative and accusative singular (they're all in the weak grade). In the plural, they inflect like all other nominals.
