J: justfab.com (I find it funny that this was what came up because I'm pretty sure I've only been on this site once.)
N: (no specific link for this letter, but rather a search for normed vector spaces... math major problems)
Q: (there wasn't a specific link for Q either but rather a Google search option for the quotient rule... again, math major problems.)
X: (Google didn't come up with anything for this letter, which isn't really surprising.)
Things I didn't need the internet to tell me: I'm a math geek, I like to craft and look at other people's crafty creations, I love reading and music, and I waste too much time on social media.
