Quechua uses a very transparent system when it comes to numbers.
Unfortunately, Quechua numbers are less and less used in everyday speech, from 1 to 10 are still widely used, and also multiples of 10, multiples of 100 and 1000, but, for example, to express amounts of money other than round numbers, many people prefer to use Spanish numbers, which are perfectly understood among the majority of Quechua-speakers.
