The * in the If statement is confusing me, is it the same as And, OR, or Either as it relates to the rngC.Value

What exact does the If statement say?

In my test to try to understand the statement I kept getting Type mismatch errors. Using A1 and B1 then pulling down to produce a small data set to apply the code to, and using = or < "xx" instead of 99. Using numbers only seems to prevent that.

The col 46 = col 49 I understand.

Thanks.

Private Sub Worksheet_Calculate()
Dim LRow As Long
Dim rngC As Range

LRow = Cells(Rows.Count, 61).End(xlUp).Row
For Each rngC In Range("BI1:BI" & LRow)
If rngC.Value * rngC.Offset(, 1).Value = 99 Then
Cells(rngC.Row, 46) = Cells(rngC.Row, 49)
End If
Next
End Sub
