Sum of the first 50 terms of 1/(n(n+1))

  1. how would you solve for the sum of the first 50 terms of 1/(n(n+1))
    I know how to do it if there is a common denominator--but i cant seem to find one here, can someone please help(btw, question on a test i just had that i couldt figure out, not hw)

    Are you familiar with partial fractions? If so then you can do the sum very easily! :)
