The cardinality of set "M" is 100. Each element is worth one dollar.
Make 100 dots representing the elements of the set "M."

Laba diena, "Minčių sodo" nariai,

labai įdomus laiškas, ačiū.

Gal kas iš mūsų šiuo metu yra laisvesnis ir galėtų šiuos
jumoristinius-matematinius uždavinius išversti į lietuvių kalbą?

Dar įdomiau būtų pabandyti sugalvoti panašių uždavinių su lietuviška
potekste, gal kam pavyktų?
