what does i stand for in algebra?

---THIS IS THE CORRECT ANSWER!!---\n\nIn algebra, the letter "i" relates to the term imaginary.  "i" actually is a shorthand for the square root of -1. Real numbers includes any number positive, negative, or zero, rational or irrational. Basically, any possible number you can think of on a number line. A non-real number would then be imaginary, a complex number whose square is a negative real number.

It means "raise to the power" - (how times you want multiply a number by itself) It has the same function as writing a superscript number afterwards.\n\nE.g., x^2=x*x is x "squared"\nx^3 = x*x*x is x "cubed"\nx^4 = x*x*x*x is x "to the fourth"

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.

In general, it means "10 times."\n\nIn math/algebra, it means "10 times a number", but you don't know what the number is, so a letter is placed there: X.

Algebra (from Arabic: الجبر, al-ğabr) is a branch of mathematics concerning the study of structure, relation and quantity. Elementary algebra is often taught in high school and gives an introduction to the basic ideas of algebra: studying what happens when numbers are added or multiplied, and how to make polynomials and find their roots.\n\nAlgebra is much broader than elementary algebra and can be generalized. Rather than working directly with numbers, one can work with symbols or elements of some set. Addition and multiplication are viewed as general operations, and their precise definitions lead to structures such as groups, rings and fields.\n\nMathematics can be defined as the logically rigorous study of topics such as quantity, structure, space, and change. Another view, held by many mathematicians, is that mathematics is the body of knowledge justified by deductive reasoning, starting from axioms and definitions.\n\nMathematics is used throughout the world in fields such as science, engineering, medicine, and economics. These fields both inspire and make use of new discoveries in mathematics. New mathematics is also created for its own sake, without any particular application in view.\n\nThe word "mathematics" comes from the Greek μάθημα (máthēma) meaning science, knowledge, or learning, and μαθηματικός (mathēmatikós), meaning fond of learning. It is often abbreviated math in the U.S. and Canada and maths in Britain and many Commonwealth countries.\n\nThe evolution of mathematics might be seen to be an ever-increasing series of abstractions, or alternatively an expansion of subject matter. The first abstraction was probably that of numbers. The realization that two apples and two oranges have something in common, namely that they fill the hands of exactly one person, was a breakthrough in human thought. In addition to recognizing how to count concrete objects, prehistoric peoples also recognized how to count abstract quantities, like time -- days, seasons, years. Arithmetic (e.g., addition, subtraction, multiplication and division), naturally followed. Monolithic monuments testify to knowledge of geometry.\n\nFurther steps need writing or some other system for recording numbers such as tallies or the knotted strings called khipu used by the Inca empire to store numerical data. Numeral systems have been many and diverse.\n\nFrom the beginnings of recorded history, the major disciplines within mathematics arose out of the need to do calculations on taxation and commerce, to understand the relationships among numbers, to measure land, and to predict astronomical events. These needs can be roughly related to the broad subdivision of mathematics, into the studies of quantity, structure, space, and change.\n\nMathematics since has been much extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both.\n\nMathematical discoveries have been made throughout history and continue to be made today. According to Mikhail B. Sevryuk, in the January 2006 issue of the Bulletin of the American Mathematical Society, "The number of papers and books included in the Mathematical Reviews database since 1940 (the first year of operation of MR) is now more than 1.9 million, and more than 75 thousand items are added to the database each year. The overwhelming majority of works in this ocean contain new mathematical theorems and their proof."\n\nArithmetic or arithmetics (from the Greek word αριθμός = number) in common usage is a branch of (or the forerunner of) mathematics which records elementary properties of certain operations on numbers, though professional mathematicians often treat arithmetic as a synonym for number theory. It is the oldest and simplest branch of mathematics, used widely by almost everyone from simple daily counting to more advanced science and business.\n\nGeometry (Greek γεωμετρία; geo = earth, metria = measure)

algebra is practically easy...i myself am in algebra one, and im in 7th grade, if you have the math book for it, inside is a URL for an internet site that you can go to for extra help on the concepts and skills, and it won't just give you the answers, it will work out the problem with you, to let you know what to improve on.

Simple algebra question:\n\na^2 + (a+1)^2 + (a+2)^2 = (a+3)^2 + (a+4)^2\n\nMultiply everything out getting...\n\na^2 + (a^2+2a+1) + (a^2+4a+1) = (a^2+6a+9) + (a^2+8a+16)\n\nAdd like terms on each side...\n\n3a^2 + 6a + 5 = 2a^2 + 14a + 25\n\nAll terms to the left...\n\na^2 - 8a - 20 = 0\n\nFactor into...\n\n(a-10)(a+2) = 0\n\nSolutions are a=10, or a=-2.  Since a has to be a positive integer, a=10.\n\n10,11,12,13,14 are your answers.\n\n\nCHECK:  \n\n10^2 + 11^2 + 12^2 =? 13^2 + 14^2\n\n100 + 121 + 144 =? 169 + 196\n\n365 = 365.

I have no idea what you're trying to ask!  This looks a little like a math question.  Does the "i" in your question stand for an imaginary number?

The order of operations is PEMDAS, best remembered by "Please Excuse My Dear Aunt Sally".  It stands for Parentheses, Exponents, Multiply, Divide, Add, Subtract.\n\nUsing this, you would solve the equation as follows:\n\n1) Parentheses: Take (x2-3y) first. Insert x and y values to get (-1 x 2 - 3 x -2).  Based on the order above, you need to multiply within the parentheses first. So you take -1 x 2 = -2.  3 x -2 = -6.  This leaves you with -2 - -6.  Subtracting a negative gives you a positive, so you have -2 + 6= 4.  The answer to the parentheses is 4.\n\n2) Multiply the end of the equation, the -4y3.  This becomes -4 x -2 x 3.  This gives 24.  (negative times negative equals positive).\n\n3) Before you divide, simplify the right side by combining like terms. 5 + x + 24.  So, 5 + -1 + 24 = 28.\n\n4) You now have 4/28.  This reduces to 1/7. That is the answer, 1/7.  (Sorry I had it wrong before.)
