Algebra 2 is usually 2nd year Algebra.  You cannot take #2 until you have taken, or can test out, of #1.\nSimilar for Calculus 3 -- it's the 3rd level of Calculus and you can't take it until you've completed, or tested out of, Calculus 1 and Calculus 2.

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.

If you're taking the course through a bricks-and-mortar college, see if the college has math tutors available.  \nIf you're taking the course online or your school does not have tutors, there are websites online with free worksheets to help you with troubling concepts. Try one of the following or search google for "algebra help":\n\nhttp://www.algebrahelp.com/lessons/\nhttp://www.algebra.com/\nhttp://www.purplemath.com/\n\nIf it's really troubling you and worksheets just aren't cutting it, try purchasing a game from Best Buy or another computer store that focuses on Algebra skills.  They really do help.

An expression is a combination of numbers, operators, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables arranged in a meaningful way which can be evaluated. 5+4 and 1/x+3 are both expressions.\nWhereas an equation is a mathematical statement that sets two expressions equal to each other; 2x-9=3x+17 is an example of an equation.

Basic math/algebra. You are taking two known numbers and finding the unknown number. \nE=P/I  solve for I    Think like simple Algebra I is X. So you want to work the problem and get a final answer x=?  or   I=?\nHope this helps.

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.

We don't actually use vectors in our every day lives, though we learn all about them during our flight training. As far as algebra II, we never do any math which is that complicated.

If you're talking about algebra I, you are probably dealing with quadratic expressions like the following:\n\nx^2 + 7x + 6\n\nThese are a bit like a puzzle.  If the number in front of the x^2 term is 1 (as in the above example) then the puzzle is like this:\n\nLook at the 7 and the 6.  What two numbers multiply to 6 and ad to 7?\n\nConsider all the pairs of numbers that multiply to 6\n\n1,6 or 2,3.  Which pair adds to 7? The 1 and 6.\n\nSo the above equation factors to (x + 6)(x + 1)\n\nAnother example is x^2 - 6x - 16\n\nThe ques ion becomes what two numbers multiply to -16 and add to -6.\n\nThe pairs of factors of -16 are \n+ or - 1 and 16\n+ or - 2 and 8\n+ or - 4 and 4\n\nWhich pair of these factors add to -6?  With a little checking you can see the pair is -8 and +2\n\nSo this equation factors to\n(x - 8)(x + 2)\n\n\nThis even works for equations like the following:\nx^2 - 16\n\nWhat you have to remember is that this can be re-written as\n\nx^2 + 0x -16\n\nSo, what multiplies to -16 and add to zero.  Use the last example and you should see this one for yourself.\n\nGood luck.

breaking it apart, we have:\n\n(x+1)^3=(x+1)(x+1)(x+1)=\n(x^2 + 2x + 1)(x+1) =\n(x^3 + 3x^2 + 3x + 1) SO\n6(x+1)^3 = 6(x^3 + 3x^2 + 3x + 1) = 6x^3 + 18x^2 + 18x + 6\n\n(x+1)^2 = (x+1)(x+1)=\nx^2 + 2x + 1   SO\n-3(x+1)^2 = -3(x^2 + 2x + 1)=\n-3x^2 - 6x - 3\n\n4(x + 1) = 4x + 4\nand -9 stays the same.\n\nSo putting everything together, you have\n(6x^3 + 18x^2 + 18x + 6) + (-3x^2 - 6x - 3) + (4x + 4) - 9 \ncombine like terms and you get:\n6x^3 + (18x^2 -3x^2) + (18x - 6x + 4x) + (6 - 3 + 4 - 9)\n6x^3 + 15x^2 +  16x - 2\n\nWHEW!  That took me back to college pre-calc!

Algebra is basically adding subtracting or dividing deppending on what is being asked such as simple algebra: x= -3x+12. The way you would do this is:  subract the 3x and bring it over to the x. ( 4x=12) then divide (x=3). Than that means obviously x equals 3. you just need to solve by adding like terms such as x's and integers. The concept is getting something to eual a letter. Then if it asks "Solve for X" go 1 more step add x=3 back into the equation so it would be; 3x(3)+12> 3x3+12= 21

I'm an English teacher, and even I occassionally need to use algebra... but believe it or not, the most important thing they want to teach you in algebra isn't math.  It's problem solving and critical thinking skills.  You'll use those skills in whatever direction you take after high school.

Abstract algebra is the field of mathematics concerned with the study of algebraic structures, such as groups, rings, fields, modules, vector spaces, and algebras.\nLinear algebra is the branch of mathematics concerned with the study of vectors, vector spaces (also called linear spaces), linear transformations, and systems of linear equations in finite dimensions.\nIn abstract algebra, a Boolean algebra is an algebraic structure (a collection of elements and operations on them obeying defining axioms) that captures essential properties of both set operations and logic operations. Specifically, it deals with the set operations of intersection, union, complement; and the logic operations of AND, OR, NOT.\n\nCollege algebra covers Algebraic operations, Equations and inequalities, Functions and their properties, Number systems and operations.\nThe easiest one is College Algebra

In mathematics, a polynomial is an expression in which a finite number of constants and variables are combined using only addition, subtraction, multiplication, and non-negative whole number exponents (raising to a power).

algebra is the solution of equations like the above.  Let the "what" be expressed as w.  Then the question becomes\n\n  w * 3 = 4/3\n\nNow how do we solve this for w.  The trick is to operate on both sides of the equation the same function.  The caveat is that the function applied must have an inverse.  In this case multiply both sides by (1/3).\n\n(1/3)*3*w = (1/3)*(4/3)\n\nNow since 1/3 is multiplicative inverse of 3, the result is 1, and since 1 is the multiplicative identity, the result of the left hand side is w.  For the right hand side just do the multiplication\n\nw = 4/9\n\nThus 4/9 multiplied by 3 equals 4/3.
