Using of Logarthims in my schoool days

Hi Yugasini! I used log tables, and I also used log scale! Do you remember the scale, it was much easier to carry. But to be honest, I hated math. :) I really don't know how I got this far. :) Well, not actually hated it. I understood it, but was simply too lazy to revise it. :) If I went to school at this stage with all my maturity, may be I would fare better. :) Happy New Year to you and your family. :)

we used logarith books last year in primary school but this year we use calculators but i like calculators more because it saves some time but i had other things written in my book so...

I know what they are, but I don't use them. I haven't done any algebra or geometry or anything beyond basic math since I left school.

Hi Yugasini. We did not use calculators when I was in school, either. We memorized math tables and formulas and solved problems using those things on paper with a pencil. We did not have logarithm books, either, so I am not familiar with them. This, too, was in the 1960s. Karen

wow that is really nice. You know what, I missed that topic in school. I don't know where it went...lol One thing is for sure,it didn't reach my head.lolz.. I can't even remember if it had been a part of our lesson in school. Well, it is not too late to learn new things. I may check on that and see how to compute using Logarithms. Happy Lotting!

A logarithms is basically the inverse of an exponential. Let's use a simple example.We all know that 3 square is 9 ,right As in 3^2 = 9 Suppose you didn't know that and needed to find that what exponent 3 needs to get 9 in other words 3^x=9 we want to find out what x is Logarithmic will do this for us.All you need to do is take the log of 9 to base 3 and it will give you the answer Log (3)9=2 The 3 in bracket should written in little font but that's not an option here. That's basically all there is to it.There are few laws which describe hoe they work,but they'll come in practice.To get a log on your calculator,just make sure you know the change-of base law. Most Calculator don't let you specify the base of logarithm, so use the law log(a)9/log(a)3=log(3)9 it doesn't matter what (a) is,so long as it is the same The log button in your calculator is log(10)

I have never heard of such a thing. It does sound very interesting. Maybe it wasn't in use in the U.S. I have no idea. Tell me more about it. Do you have the right spelling? Purrs, Catwoman=^..^= & Mija

Hi yugasini garu Even I use to calculate the maths with the help of logarithm book only while studying in the school. But since I do not like that subject, I do not bother to remember them. Now that so many years have passed, I totally forgot about it anyway
