I like learning the mathematical words in Finnish. I know in English there are squares and cubes of numbers. How would we say 4 squared? I know it’s the same problem as 4 times 4 but it’s a way of saving a little space on paper.


Inge (admin)

4² = neljä potenssiin kaksi
2³ = kaksi potenssiin kolme

Inge (admin)

The way I originally offered to say these squared forms is quite formal. I understand that for 4² you could also so “neljän neliö”, 6² would be “kuuden neliö”.

For higher numbers, you can also use ordinal numbers in the mihin form: 2³ would be “kaksi kolmanteen”, while 4⁴ would be “neljä neljänteen”.

Hope this helps!
