    [latex]5+3[/latex] [latex]-5+\left(-3\right)[/latex]
    Both positive, Sum positive Both negative, Sum negative
    When the signs are the same, the counters would be all the same color, so add them.
    [latex]-5+3[/latex] [latex]5+\left(-3\right)[/latex]
    Different signs, More negatives Different signs, More positives
    Sum negative Sum positive
    When the signs are different, some counters would make neutral pairs; subtract to see how many are left.
