Questions & Answers about Kaksi ja kaksi on neljä.
Why does the sentence use the singular verb on instead of the plural ovat?
In English, we sometimes say "two and two ARE four," but Finnish math equations always use the singular verb on (is). Think of it as saying "the total of two and two is four."
Why are kaksi and neljä in their basic dictionary forms here?
When you are just talking about the numbers themselves, like in a math equation, you use their basic form. You only need to use special word endings (like the partitive case) when you are counting actual objects, for example when saying "two cats".
Will I always hear Finns pronounce kaksi exactly like it is spelled?
Not usually! In everyday spoken Finnish, people almost always shorten kaksi to kaks. So in real life, you will probably hear this spoken as "kaks ja kaks on neljä".
