I can't believe you're asking this. "Do I make her my arithmetic WHORE or do I tell her no, I simply can't do it, or do I just try to help her so maybe she'll actually try something on her own?" Wait, the third one isn't an option, so I'll go with lazy answer without benefits to yourself. Gosh is she lazy, and what are you going for? Something tells me you're a lot smarter to know what's "right" and what's "wrong." People disgust me.
