Hm. I get the feeling that you aren't exactly legit friend.
For instance, your spelling is rather...bad for a Senior. Also, I am a Junior in High School, 11th Grade, and I already know, long division is not a thing in High School. That's grade and middle school. High School consists of Algebra, Geometry, pre-calc, the works. Also, calculators are almost required in these classes, so you wouldn't have to worry about long division.
Not trying to start an argument, but, well, I am just saying it like I see it.
Your old friend,
Commando
