Consider [x] as the greatest integer function of x and {x}=x–[x].
Evaluate ∫{√x} dx for x=1 to 484.
NOTE: The greatest integer function is defined as a function that produces the "greatest integer less than or equal to the number" operated upon, symbol [x] or sometimes [[x]]. If the number is an integer, use that integer. If the number is not an integer, use the next smaller integer.

question by Stefan)
The math symbol thing never works for me, either, so I just use ASCII versions of operators, or spell them out, when I post comments. I use sqrt(x), a^b, x_1, x_2, etc. and just say sum of ... over k from 1 to n, and similarly for products and integrals. Mathematics is notions, not notations (Gauss). When you submit problems, things are better because some HTML tags are allowed. The reason why the math symbols don't work may be that the browsers we use are not the ones that are compatible with them, or maybe the whole thing is just general lameness of the editor tool provided for our comment input. It is a known problem, presumably, that the powers that be have not so far been able to address adequately.
