    So to concatenate in excel, use the ampersand (&) as in: [=A1&” -Under “&B1] to concatenate a number in A1 with the text ” -Under ” and a number in B1.

    To de-concatenate, specifically for a stem and leaf plot, use Left(cell, number) as in: [=Left(A1, 2)] which will take the first two digits of the number in A1.

    These two functions help a lot in Excel.
