Symmetrical values

Hello,
I would like to know if there is a way, through formulas or conditional formatting to identify symmetrical values. For instance, 1 and -1, 100 and -100.
Calculate the absolute value won't work because there is a risk to identify and remove repeated values, for instance if I have three cells with 5 but only one cell with -5.
Thanks and regards

    It could be 

    =SUM(--(C2=-$C$2:$C$18))*IF(C2>0,COUNTIF($C$2:$C2,C2)=1,1)

    which highlight only FIRST met positive number and ALL symmetric negative numbers for each pair. If only first negative is needed, when instead of IF use only COUYNTIF within it.

      Thank you for the solution.
      However it gets a limitation: when the database has multiples entries with the same positive value (as per attachment) it automatically highlight all the entries and I just need to highlight t one of them in order to clear the negative one.
      Do you have any workaround?
      Thanks

    The sort of formulas that might help are

    = COUNTIFS(values, values)
    and compare with
    = COUNTIFS(values,-values)

    If you use MS365 then you can filter the numbers and compare the count of positives and negatives

    = COUNTIFS(values, UNIQUE(ABS(values)))
    and
    = COUNTIFS(values,-UNIQUE(ABS(values)))
