table of natural logarithms

This table is for integers in the range . To find the natural logarithm (that is, with base $e$, the natural log base) for the desired $n$, look for the ten’s place digit (0 in the case of ) in the leftmost column and the one’s place digit in the topmost row. The intersection $x$ of that row and column thus gives $\log n$ to four or five decimal places.
