        I assume that I14:I16 contain numeric values.

        LEFT(B3,2) returns a text string such as "50".

        Text strings don't match numbers.

        The first minus sign converts the text string "50" to the number -50.

        The second minus sign converts -50 to 50.

        We could also have used 1*LEFT(B3,2) or 0+LEFT(B3,2). All of these force Excel to convert the text string to a number.
