Oksana Neveselaya is an esteemed University of Kiev graduate and well-liked math teacher. She's also probably the hottest single equation-solving native of Belarus you're likely to get a look at today, if not ever.
It doesn't hurt that Neveselaya has supposedly described herself as a "sensual" math teacher—that alone would be enough to make it clear she's aware of just how high her hotness quotient truly is—but we also have her Instagram, which is a decidedly non-academic delight.
That's just a taste of what Oksana's Insta has in store. We suggest you get over there and do your homework on her.
