Recently when I talked to a professor specialized in number theory, I learned about normal numbers.(adsbygoogle = window.adsbygoogle || []).push({});

So the other day I asked myself, is the sum of two normal numbers still normal? I quickly realized if you take [tex]\sqrt{2}[/tex] and [tex]-\sqrt{2}[/tex] you get 0 so the answer is obviously no.

But then I started to wonder, what if we know the sum is an irrational number? is it then normal?

I am intuitively guessing that the answer is yes...

Thanks in advance for any input!
