Learn Portuguese (Portugal): Há um problema?

It's a common beginner trap! While Portuguese words ending in "-a" are usually feminine, many words ending in "-ma" are actually masculine. This includes um problema, um programa, and um sistema. Because the noun is masculine, we must use the masculine indefinite article um.

How does the word Há translate to "Is there"?

Há is a very common word that means "there is" or "there are". In a question, it simply translates to "is there" or "are there". Remember that the letter "h" is always silent in Portuguese, so it is pronounced exactly like "ah".

In English, we change "there is" to "is there" to ask a question. Why does the Portuguese sentence stay the same?

In Portuguese, you don't need to change the word order or add extra helper words to ask a question. You just take the normal statement (Há um problema = There is a problem), add a question mark, and raise the pitch of your voice at the end when speaking.

If I wanted to ask about multiple problems, would I use uns or umas?

Because problema is masculine, you use the masculine plural article uns to say "some problems" (uns problemas). The word Há never changes for plurals, so the question becomes Há uns problemas? (Are there some problems?).
