A function, r, is defined as r(n) = (n-7)[(n+1)-7][(n+2)-7]... where n is an integer. What is the value of r(1)?
How do you do this?

  1. r(n) = (n-7)[(n+1)-7][(n+2)-7]
    r(1) = ....
    wherever you see an n, replace it with 1
    r(1) = (1-7)[(1+1) - 7][(1+2) - 7]
    just work it out. Watch the order of operation, let me know what you get.
