## Main Question or Discussion Point

Hi, i'm taking calculus this sem, and i have a question on stuff pre calculus.

If x and y are natural numbers and y[less-than]x, then whole numbers q and r must exist such that x=yq+r.

a)what is the value of r if y is a factor of x? IT IS ZERO

b)If y is not a factor of x, what are the possible values of r if y=5 , y=7, or y=n???

I dont get b), can anyone help me plz.

THANK YOU.
