# table of common logarithms

This table is for integers in the range $-1<n<100$. To find the common logarithm (that is, with base 10, the same base of our numeral system) for the desired $n$, look for the ten’s place digit (0 in the case of $-1<n<10$) in the leftmost column and the one’s place digit in the topmost row. The intersection $x$ of that row and column thus gives $\log_{{10}}n$ to four or five decimal places.

$n$ | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
