5th through 8th grade math
There is nothing complicated at all about what I'd wrote, all based on 5th through 8th grade math, and nothing more, try not to look at the triangles and arrows if you’re having problems with the math.
I understand what you’re saying ‘Joy’, and it is puzzling, but it’s obvious he needs help or he wouldn’t asks? I don’t think he’s trolling; it just doesn’t come off that way, not insinuating that you think he is ether (trolling).
To me, it wouldn’t make a difference if he has a teacher or not. It is tradition that a warrior who understands himself and the way of combat would prefer only to help then hurt.
I’m not trying to take anything away from you at all. you know your stuff.
