Mathematics Earlier, around 1960, the license plates were formed only by a figure representing the city in this case 7, followed by two dozen. Then there was a change in the system and the plates now have two letters followed by four digits. In this system, the two letters indicated the city. It, if someone committed any negligence in traffic, just looking at the initial letters of the plate, since you can not always read the small print indicating the name of the city, people joked "had to be ..." (City name). Currently, as the plates are formed of cars? What is the logic of the national license plate? What is the initial letters? With the increase of the fleet, the plates in the 1990s had new change, now have three letters followed by four digits, and today the letters are set by the Brazilian state. The letters that may be used are 23 of our alphabet and: k, Dewey, and the numerals 0 to 9. The new system began specifically in the city of Curitiba, and so, in Paraná, the plates start up with the letters A and B. ACTIVITY Write some license plates and see if a plate may differ from another only because it presents a different element, or by having the same elements with the order changed. Without considering the existing rules for states or cities, how many plates were possible form using two alphabet letters and four digits? And if you use three letters and four digits? Compare and discuss the results.

Matematika Ranije, oko 1960, registarske pločice su formiraju samo lik predstavlja grad u ovom slučaju 7, a nakon dva tuceta. Tada je došlo do promjene u sustavu i pločice sada imaju dva slova slijede četiri znamenke. U ovom sustavu, su dva slova naznačeno grad. To, da je netko počinio bilo nemar u prometu, samo gleda na početnih slova na ploču, jer ne možete uvijek pročitati sitni tisak navodi ime grada, ljudi se našalio "morao biti ..." (Grad naziv). Trenutno, kao što su tanjuri formirana automobila? Što je logika na nacionalnoj registarske pločice? Što je početna slova? Uz povećanje flote, ploče u 1990 imala novu promjenu, sada imaju tri slova slijede četiri znamenke, a danas su slova su postavljene od strane brazilske države. Slova koja se mogu koristiti su 23 od naše abecede i: k, Dewey, a brojevi 0-9. Novi sustav je počeo upravo u gradu Curitibi, i tako, u Paraná, ploče pokrene sa slovima A i B. AKTIVNOST Napiši neke ploče licenci i vidjeti ako ploča može se razlikovati od drugih samo zato što ima drugačiju elementa, ili imaju iste elemente s promijenjenim redoslijedom. Bez obzirom na postojeća pravila za državama ili gradovima, koliko je tanjuri bili su mogući oblik pomoću dva abecedu slova i četiri znamenke? A ako koristite tri slova i četiri znamenke? Usporedite i raspraviti rezultate.
