Log tables and antilog tables

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

NOTE:

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

To prove this

Find the antilog of `10^0.3506`

Using antilogarithm tables

Using anti logarithm tables

`2.239 +3 = las\t \ digit = 2.242`

`10^0.3506 = 2.242`

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

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

`= 2.242`

Conclusion

Same number found but slightly more difficult
