Ms. Sue,
Please click Post a New Question and then ask your question. Also  your question isn't clear. What exactly does Matthew need to know about division? Do you also want to know about how to borrow in subtraction problems?

bobpursley,
For each point to be rotated, use this set of equations:
x'=x*cos(theta)+y*sin(theta)
y'=x*sin(theta)+y*cos(theta)
where x,y is the original point, and theta is the chosen angle of rotation counterclockwise.
