Have a feeling she likes me?

So there is this girl in college who is in the same club as me. I have a feeling she likes me but at the same time I'm not sure. I feel comfortable touching her and being around her. Whenever I pass by her, she's always like smiling at me. I jokingly hit her on the head and she avoids it and giggles. One time she even whispered something to me, which was kind of cute. When I'm alone with her, I feel like she's trying to talk to me. I don't see her doing this with other guys I think. One of the weirdest thing she asked me was what "40 + 45" is...,, which is obvious? Is she trying to talk to me? Sometimes I feel like she sits like close to me on purpose but doesn't say anything or pretends not to see me?

But at the same time, I feel like she kind of doesn't. She walked by me once without saying anything and i said hi. One day she completely ignored me (which I found weird because we had a good chat the day before) but then showed interest the next day, like getting close to me or 'accidentally' bumping into me.

Any advice would be appreciated. You can post your question too. Its a lot easier to get advice from someone else.

Thanks
