I've seen so many of the these little quirks that are supposedly ADHD related that I can't tell if I have it 

or people are just calling every quirk they have ADHD just because they have it, therefore everything they do must be because of ADHD

It’s probably the second one. This example is not an actual indicator of ADHD, but rather basic math reasoning. Take 101+101 for instance. How did you solve that in your head? If people didn’t have a process for solving this problem, they would have to memorize every single question, instead of intuitively knowing what to do because the human brain is so good at recognizing patterns.
