Talk:1984 AIME Problems/Problem 7

The AOPS topic had the formula written as

f(n)= $$\{\begin{array}{ll}n-3& \text{if }n\ge 1000\\ f(f(n+5))& \text{if }n<1000\end{array}$$

If you look at this page, you can see about halfway down the page under the heading "Cases and distinctions" that the "\text{if }", which causes a problem in AopsWiki, should be replaced with "\mbox{if }".
