Not sure about the math, but you can touch my dick anytime...

Awesome. Pure awesome.

One of the best Eremin fics I've ever read. Wow, just... Wow.

I hate math, and most of this was gibberish I can't even remember. But I wish I had a study partner like that. ;)

Armin is a pretty good tutor. Imagine some of their other friends asking how Eren got so good at trig...
Geez awkward!

Damn, I could really use Armin to help me with math.

Oh my frog. Math. Ugh. But seriously, Armin was TOO yummy in this. Like, hello? Can he not be like this in EVERY fic? I loved it! But I was pretty sad at how fast they came. I literally 'Aww'ed. That was a perfect way to remember the formulas though! If I could do that Math and I could finally be friends XD But seriously, super sexy Armin. Love it

When i was learning this in class, i got a 62% on the test
after having read this, i think i understand trig identitiea more than i did when my teacher explained it to me

Man i wish i'd read this fic before my trig test... that way maybe i wouldn't do so bad.
Good story :)

Maths always have been the worst nightmare of mine, so maths in foreign language should be a real apoccalypse, but surprisingly... it was not! :D
Great fanfic! The bossy Armin is really interesting
Keep your (flawless) work H.W.! I love it :)

The First non-Hetalia Fic that made me want to study.
Oh, and just a technicality issue: sin(x)*cos(y)-cos(x)*sin(y) is not sin(xy)...it is equivalent to sin(x-y)...
I know...I'm being that person again...

Hot damn this fic was good. Like Jesus Christ everyone was well written and the sEX WOW ugh I think I'm in love

I saw the summary to this and I was just- "I am so reading this, I hate math but there's dicks and ermin" And ooooh boy was I happy to read this, this made me hate it just a teeny bit less

Armin was so teasing and sexy /!

Eren had to try hard not to force himself on Armin, right!?

I shouldn't have liked that as much as I did oh m d ygod
