Has anyone found a practical appilcation for the use of algebra in the real world?

Algebra and all the Maths that one learns at school and college are tools which are ultimately used by Scientists, engineers, doctors, and almost all the people who have something to do with science. Even social scientists like historians and sociologists use it. \n\nIt may seem abstract but Maths is the underlying machinery of the Universe.

I am not sure what you actually want to do. Do you want a package that does calculus? Then what is wrong with Mathematica? \n\nI have used several different computer algebraic manipulators, like MACSYMA and REDUCE and MUMATH and SMP and so on. There are some advantages and disadvantages to each. But Mathematica is not a bad choice and is well supported.

Until you change your mind about math, you're not going to be able to help, no matter how much you want to.  Algebra isn't bizarre.  It's actually a pretty basic way to find an unknown. And you use it every day without realizing it.   For example, let's say you have $1.00.  You go to the store to buy apples.  They each cost 20 cents.  How many could you buy for $1.00?  That's algebra in its most basic form.  \n\nSolving algebra problems is no different than solving any other math problem.  Begin by breaking it down into what you know and what you need to know.  And always remember that whatever you do to one side of the equation must be done to the other side. \n\nTo help with your son's work, do it together.  He needs to learn the process more than he needs to get the right answer.  Work problems together and talk them out.  You'll learn from one another, and you'll really cherish the time together.

The commonly taught method for computing square roots with pencil and paper can be found in the Wikipedia article, "Methods of computing square roots".\n\nScroll down to the heading "An exact long-division-like algorithm".

looks like straightforward algebra, and isn't really relevant whether the formulas are electrical

modern algebra is used in all scientific fields on almost a daily basis.  Its used everyday by the financial world in calculating interest and money values.  its used by the social sciences to study trends with society. A cashier at a store uses it when she rings up your order (the machine does it for them in most cases) Its basically used by everyone, everyday.

Yes, i learned basic algebra in junior high.\nI see no reason why a high school senior would be incapable of learning it.

Wow, there is a lot here!  I'll start with some tips for solving algebra problems.  The first thing you should always remember is to play the equal game.  Whenever you add, subtract, multiply, or divide, you should do the same to the other side.  The other tip is to use the order of operations when simplifying.  Remember the sentence: Please excuse my dear Aunt Sally.  The initial letters of each word stands for the order of operations.  Do the Parenthesis first, followed by the Exponents, then Multiplication or Division, and Addition and/or subtraction next.  Finally, you should always simplify first using the order of operations before you start shifting numbers from one side of the = to the other.  \n\nI'm not going to work all of these problems, but I'll show you a few to get you started.\n\n1)\n3x-7 = 2   Add 7 to both sides\n3x = 9   Divide by 3\nx = 3\n\n4)\n6x - 3 = 2x - (4-3)/3   Simplify the stuff inside the parenthesis first\n6x - 3 = 2x - 1/3  Add 3 to both sides\n6x = 2x - 5/3  Subtract 2x from both sides\n4x = -5/3  Multiply both sides by 3\n12x = -5  Divide both sides by 12\nx = -12/5\n\nI hope this helps.  Good luck!
