Current please help

    Current...please help!!!

    1. The problem statement, all variables and given/known data

    In an ionic solution, 3.93×10^15 positive ions with charge +2e pass to the right each second while 9.01×101^5 negative ions with charge -e pass to the left. What is the magnitude of current in the solution?

    2. Relevant equations

    I = Ch in Q / Ch in T

    3. The attempt at a solution

    So I did...
    R = 1.6x10^-19 * 3.93x10^15 / 1
    R = -1.6x10^-19 * 9.01x10^15 / 1
    and then I added them...what am I doing wrong???
