Welcome to free math tutoring, It's a little like what you do when you invent a board game like chess. You specify that there are such-and-such pieces, and they can move in such-and-such ways, and then you let people explore which board positions are possible or impossible to achieve. The main difference is that in chess, you're trying to win, while in math help, you're just trying to figure out what kinds of things can - and can't - happen. So a 'chessamatician', instead of playing complete games, might just sit and think about questions like this: If I place a knight (the piece that looks like a horse, and moves in an L-shaped jump) on any position, can it reach all other positions? What is the minimum number of moves that would be required to get from any position to any other position? Think, get more examples on free online math tutoring.

Chess related to math
Introduction of Mathematics
I am your math helper,
mathematics is the derivation of
theorems from axioms.
So what does that mean?
It means that mathematics is a collection of extended, collaborative
games of 'what if', played by mathematicians who make up sets of rules
(axioms) and then explore the consequences (theorems) of following
those rules, more examples in math forum,
For example, you can start out with a few rules like:
A point has only location.
A line has direction and length.
Two lines interesect at a point.

multiply matrices
Let us learn about multiply matrices
If we multiply matrices, that must be present in same or different order. Let us consider we add matrix B by matrix A. If matrix A has 3X 3 orders, the matrix B also present in 3 X3 orders or other order like 2 X2. In matrix multiplication multiply every row of first matrix by every column of second matrix.
In our next blog we shall learn about ammonia solution I hope the above explanation was useful.Keep reading and leave your
Different numbers in India
The Hindu-Arabic numeral system is a positional decimal numeral system. Many of the countries adopted the Indian numerals.
Most of the positional base 10 numeral systems in the world have originated from India, where the concept of positional numerology was first developed. The Indian numeral system is commonly referred to in the West as the Hindu-Arabic numeral system or even Arabic numerals, since it reached Europe through the Arabs. you can find these examples of help in math numericals below,
I hope the above explanation was useful, math forum helps you with more examples.

8th grade math worksheets
8th Grade Math Worksheets Example:
Example 1:Determine the distance between the points (-5, -5) and (1, 3).
Solution:
The distance d between points (-5, -5) and (1, 3) is given by
d = sqrt [(1 - -5) 2 + (3 - -5) 2]
Solve the above term.
d = sqrt (36 + 64) = 100

ln x
Let us learn about ln x
- For every x in the domain of f, f -1[f(x)] = x, and
- For every x in the domain of f -1, f[f -1(x)] = x
Differentiate Ln X:
Example 1: Differentiate ln xSolution: Let f(x)= ln x
Differentiating f(x), we get
f'(x) = 1/x
So, the solution is 1/x

Factor by grouping
Factoring by grouping is usually done when you have at least 4 terms and they do not look to have anything in common. The procedure for that is:
Factor by grouping, in layman language, is simply defined as the grouping of terms with common factors before factoring a polynomial. A polynomial is a mathematical expression that is formed by variables and constants. The construction of such variables and constants is done by using operations of addition, subtraction, multiplication and non-negative whole number exponents (constants). Before we get down to factor by grouping methods
In mathematics, factoring is one of the important topic in algebra. Given expression can be factored by using the method of factoring by grouping. The given polynomial expression can be factored by different methods that are factoring by grouping, using trinomials by ac method, and group the polynomials more than two groups. Let us solve some example problems in factoring by grouping.
