well, yeah, i do heal pretty fast, and thats more the reason to set the arm faster. also, it sucks typing with my right hand because i am a lefty. and also, polynomial long division only works on problems like
x" +x+3

" is the same as squared when i type.
it doesnt work with binomials or polynomials. only monomials. if you dont understand any of this, its ok. i didnt know it until last week.

we set the arm with a metal rod and some cloth, and i think its doing ok
ps. it wasnt my idea to put PLEASE PLEASE PLEASE PLEASE PLEASE. i only said one please in lower case.
