Sorry for the late reply Greg ,
I have been searching for a good Pre algebra book for the past 1 month
I tried a lot of books but there is not a single book i can still recommend .
But this website here is a good one ,
https://www.math-only-math.com/
I have been practicing from it from...
In a pdf online , i found this .
LCM
1.
Find the prime factorization of each
number in the group.
2.
Make a list of ALL factors, raised
to the HIGHEST power that appears in
any factorization.
3.
Multiply out.
GCF
1.
Find the prime factorization of each
number in the group.
2.
Make a list of...
After trying to learn computer science and numerical methods . This is what i have learned from my past experiences .
Science is a differential equation. Religion is a boundary condition - Alan Turing
Thanks for the reply ,
Found some good materials in khan academy
https://www.khanacademy.org/math/algebra2/exponential-and-logarithmic-functions/introduction-to-logarithms/v/logarithms
I have a couple of college algebra textbooks , but none has some proper intro to logarithm basics .
I like to keep a book for logarithm alone , i see some online PDF's on logarithm , but all are sort of messed up .
Please help
Mathivanan ,
Thanks for the reply .
I was mostly after finding LCD of the denominators of rational expressions and equations . I have more clarity now .
To calculate an LCM for a rational function, follow these steps:
1. Factor all denominator polynomials completely.
2. Make a list that contains one copy of each factor, all multiplied together.
3. The power of each factor in that list should be the highest power that factor is
raised to in any...
Thanks for the replies .

So ,
x is electrons
x is a quantity
x is binary
x is a point mass object
x is digital logic
Is this an OK definition ?
Steps to Find the LCM of Two or More Rational Expressions
1. Factor all denominators completely.
2...
Thanks a lot for that really long explanation .
I understand this part properly
1. Factor all denominators completely
4x = 2.2.x , x2 = x.x , 2x2 =2.x.x
So ,
2. The LCM is the "product" of unique ( being the only one of its kind; unlike anything else )"pairs of irreducible factors" from...
Thanks ,
Steps to Find the LCM of Two or More Rational Expressions
1. Factor all denominators completely.
2. The LCM is the product of unique prime factors from the denominators,
where each factor is raised to the highest power to which it appears in
any denominator.
Can somebody show me...
Thanks for the reply ,
In the first equation , why is 4x2 the LCM ? What are the steps involved to find LCM like that ?
Same question here , i don't understand taking the LCM part properly ?
OK , I have three questions
I was a computer science student , so i am a bit confused about some terms .
What is a variable x ?
x is a quantity
x is binary
x is a point mass object
x is digital logic
x is electrons
The other is when you try to find the "pairs of factors" of a number . You...
Thanks , but i was looking for something simple .
I think i found a good book online called Glencoe - Algebra 1-McGraw-Hill
It looks really good for my needs :-)
We had computer oriented numerical methods in C programming language in our syllabus , so i went through at least 5 books , lots of online materials on C .
Some books are very minimal like the Official version , The C programming Language. By Brian W. Kernighan and Dennis M. Ritchie
So , When...
Thanks for the reply ,
Currently i am only following the materials available from these resources .

Most of those resources don't have...
Methods of factoring .
Method of common factors
Factorization by regrouping terms
Factorization using identities
Factors of the form ( x + a) ( x + b)
Factor by Splitting
Is this all the factoring methods out there ? Or are there more ?
I am also looking for a book with lots of...
I also found something here
Factoring and Solving by Factoring

Thanks ,
First you have a function f(x)
Then you can take the derivative of that function from first principles
Then you get f'(x) or dy/dx
That dy/dx , the slope of the curve (derivative) at a given point is a number .
I have been unnecessarily thinking about the cause behind why...
It is ok , i sort of understand it with my new avatar .
Some points i tried to narrow down .
Differential calculus - which is looking at the instantaneous rates of change of objects with respect to some variables. We have the notion of the derivative of a function
The slope of the curve...
I keep thinking of naturally occurring things whenever i think of derivatives , differential equations and partial differential equations .Like electricity , magnetic field .
I am always like if there is a derivative in a differential equation , how could have that happened ? what could have...
