Log tables and anti log tables

Anti log tables have the same numbers in them as log tables - But in reverse


You don’t need anti log tables but if you have them it’s easier to look up.

To prove this            

Find the anti log of `10^0.3506`


Using anti logarithm tables

Using anti logarithm tables

`2.239 +3 = 2.242`

`10^0.3506 = 2.242`


Now using the reverse of logarithm tables

 Use the logarithm tables in reverse without looking at the anti-logarithm table


`0.3506\ – 0.3502 = las\t \ digit = 4`

`= 2.242`



Same number found but slightly more difficult
