Math is hard
Math is difficult. Most people would probably agree with this statement. Who can recall all of those algorithms? She most certainly couldn’t. So, when she was preparing for a math exam, she knew she’d have to find a way to pass it.

She opted to write down the equations she needed to memorize and conceal them behind her long nails. This is rather ingenious, even if we don’t encourage cheating. Hopefully, she passed, and the danger was worth it.
