Counting in Portuguese (Portugal)
Portugues (português) is a romance language from the Indo-European family. Originating from Portugal, it has evolved into different dialects and creoles in Brasil, in five African countries (Angola, Cape Verde, Guinea-Bissau, Mozambique, São Tomé and Príncipe) as well as in Macau and East Timor. Regulated by the Lisbon Science Academy (Academia das Ciências de Lisboa), it is roughly spoken by 10 million people in Portugal alone and 170 million people in Brasil where Brazilean Portuguese is in use with mostly spelling and pronunciation differences.

Portuguese (Portugal) numbering rules
Now that you’ve had a gist of the most useful numbers, let’s move to the writing rules for the tens, the compound numbers, and why not the hundreds, the thousands and beyond (if possible).
- Digits and numbers from zero to fifteen are specific words, namely zero , um , dois , três , quatro , cinco , seis , sete , oito , nove , dez , onze , doze , treze , catorze , quinze . Sixteen to nineteen are regular numbers, i.e. named after the ten and the digit, and written phonetically: dezasseis [10 and 6], dezassete [10 and 7], dezoito [10 and 8], dezanove [10 and 9].
- The tens have specific names based on the digits roots except for ten and twenty: dez , vinte , trinta , quarenta , cinquenta , sessenta , setenta , oitenta  and noventa .
- The same applies for the hundreds: cem  (plural centos), duzentos , trezentos , quatrocentos , quinhentos , seiscentos , setecentos , oitocentos , novecentos .
- Tens and units are linked with e (and), as in trinta e cinco , as well as hundreds and tens (e.g.: cento e quarenta e seis ), but not thousands and hundreds, unless the number ends with a hundred with two zeroes (e.g.: dois mil e trezentos [2,300], but dois mil trezentos e sete [2,307]). E is also used to link thousands and units (e.g.: quatro mil e cinco [4,005]).
- European Portuguese uses the long scale system in which we alternate between a scale word and its thousand. Thus, we have milhão (106, million), mil milhões (109, billion), bilião (1012, trillion), mil biliões (1015, quadrillion), trilião (1018, quintillion), mil triliões (1021, sextillion)…
