    curious summation operator problem

    Is this correct?

    \Sigma_{i=0}^nx_i(i+1)=\Sigma_{i=0}^nx_ii+\Sigma_{  i=0}^nx_i

    I feel not. I have a long summation expression (this is a simplified model of it) and I am trying to 'open' the brackets in (i+1).

    Hello, Volga!

    \text{Is this correct?}

    . . \displaystyle \sum_{i=0}^nx_i\,(i+1)=\sum_{i=0}^n\, x_i i + \sum_{i=0}^nx_i

    Yes, it is!
