Why is だ being used at the end of the following sentence?


This is the full sentence:

おかしいけど、中国人を理解するのは難しい。私は日本人を理解する方が簡単だ。

I think I was expecting something like です or よ.

I'm really confused about this だ.




だ is the informal version of です. 簡単だ has the exact same meaning as 簡単です, but
the former is less formal.

For example, 私は猫が好き **です** よ has the same meaning as 私は猫が好き **だ** よ. But you
would use です when talking to your 目上 (someone of higher social status) or in a
formal situation, where you would use だ when talking to your friends
