    yes, but the only change I would make is to write 0.1666 as 1/60 instead

    watch your notation, the summation of 1/3 is 1/3

    \[\sum_{i=1}^{4}\] is the total of those 4 partial sums

    so I calculated all of them, then summed them in the end

    Yes, your first calculation says \[\sum \frac{ 1 }{ 3 }\] which is 1/3, the summation of 1/3

    you did it correct, just the notation is slightly off

    The first one is maybe, for i=1 \[f(x _{1},~y _{1}) = 1/3\]

    not 1/3 sorry, the -10.67 you got

    and you are finding the summation for i=1 to i=4 \[\sum_{i=1}^{4}f(x _{i}~,y _{i})\]
