In mathematics, an equation is an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. In this situation, variables are also known as unknowns and the values which satisfy the equality are known as solutions. An equation differs from an identity in that an equation is not necessarily true for all possible values of the variable.
There are many types of equations, and they are found in many areas of mathematics. The techniques used to examine them differ according to their type.
Algebra studies two main families of equations: polynomial equations and, among them, linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial. Linear equations have the form a(x) + b = 0, where a is a linear function and b is a vector. To solve them, one uses algorithmic or geometric techniques, coming from linear algebra or mathematical analysis. Changing the domain of a function can change the problem considerably. Algebra also studies Diophantine equations where the coefficients and solutions are integers. The techniques used are different and come from number theory. These equations are difficult in general; one often searches just to find the existence or absence of a solution, and, if they exist, to count the number of solutions.

'Vedic Mathematics' is the name given to the ancient system of mathematics. The system is based on 16 Vedic sutras or aphorisms, which are actually word-formulae describing natural ways of solving a whole range of mathematical problems. It is a unique technique of calculations based on simple rules and principles, with which any mathematical problem - be it arithmetic, algebra, geometry or trigonometry - can be solved.

At the beginning of class, we make a pledge to stay positive and not let the math intimidate us. Well, it worked. We took that good energy and used it to solve polynomial equations of varying degrees. In a touching moment, the students said I'd be a good dad - wow - I love this work. YAY MATH!

Our discussion of linear equations was filmed in a review day for Algebra 2, yet this is a very core Algebra topic, as well as one for Geometry: creating lines in point-slope form and slope-intercept form. We cover slope, intercepts, and perpendicular slopes as well. The students really learned from this class, join them in the learning! YAY MATH! Please visit yaymath.org Videos copyright (c) Yay Math
This video tutorial shows you how to solve systems of nonlinear equations with two variables using substitution and elimination for your pre-calculus or algebra course. It contains plenty of examples and practice problems.
In this 25 minute math video you'll review how to solve two step equations, how to solve and graph multi step inequalities and also how to translate word problems. We even look at the sneaky "when solving an inequality, if you multiply or divide by a negative number, you flip the inequality". Download and attempt the the worksheet here first: http://www.mathfolio.com/alg1/eqin After completing as much of the worksheet as you can independently, check your work and answers while watching the video.

Another round of one on one It's never time its not the place. You made your mind up; I made comments meaningless Out in the hall I heard you sighing. You held every breath you felt every chain Hoping for a feeling but the feeling never came. You held every breath you felt every chain Searching for a reason, but the reason never came. Do you remember when you said? That there was nothing you would change? What better feeling and you want it all the time What better feeling and you want it What I wanted, what you needed found the two were not related I waste my time, write these lines, wait for something you can't find The feeling's all but gone but still remains tonight. A close encounter on the stair Echoes of laughter in the hall What better feeling and you want it all the time, What better feeling and you want it What I wanted, what you needed found the two were not related I waste my time, write these lines, wait for something you can't find The feeling's all but gone but still remains tonight.
