Hi:
The answer is yes. I use them just in case all the Calculators and computers in the USA get a EMP attack and take a dump.. the other reason they were printed. Was back in the 1940's to the 1970's, computers were not available to the average person so to help colleges and schools along with the business sector. these tables along with squares, square roots, cubes, and cube roots as well as trig & other tables were printed up to help them
speed up their reseach and production. which made it a whole easier then having to calulate the logarithms up and add them and find the antilog of it - in fact that is why computers were made in the first, place to print very accurate tables and it a very good story to read about. The reason they now hang around is, if something happens to all the computers we have a backup. and are still useful.
hope this help

I don't think anyone still uses log tables, to assist in calculations, as people used to do. But it is useful to understand how they work, and how to do it if you want to study maths further, so it would be used educationally, as part of your studies.
The point is to understand indices, the rules of indices and to appreciate that indices do not need to be integers, or even rational. Also to work in different bases. If you are studying maths and want to carry on, you will need this understanding later on, it's like any skill, sometimes it is not clear why you need to learn certain things at the time. For your teacher, it may just be because it is in the curriculum.

Yes most definitely in TEACHING. They are a logical progression from the TEACHING of the LAWS of INDICES and invaluable as such.
They are necessary to explain the terms CHARACTERISTIC and MANTISSA and to lead on to other NUMBER BASES.
Logarithmic scales are the base of SLIDE RULES.
ALL students of mathematics should be aware of the value of Logarithmic Tables.
As an extreme scenario, a nuclear holocaust would probably leave a few survivors but not much in the way of infrastructure. The basic knowledge of mathematics, including logarithms would enable mankind to rebuild society.
Calculator batteries would fail and solar power would be of little value in a darkened sky.
The basics of all knowledge should be preserved. Nuclear bunkers already exist with vast library stores including printed Logarithmic Tables.
Finally, religion demands a blind faith and in modern society most people have a blind faith in calculators. Without the very basic ability to carry out ROUGH mathematical operations errors go undetected.

yes=we have lunch on one every day. seriously though, i do use log tables to solve the more difficult maths calcs. good luck!

i don't know. maybe not. i have a scientific calculator. this calculator has features that could help you. there is a log button. so i think it would be quicker, rather than looking through a page or pages.

Not me personally, nor do I use trig tables. That is why I have a scientific calculator

I still have my log book in the attic, they were the days.

Yes, I use it from time to time. It contains some very useful formulas. I also use a scientific calculator.
