what is scientific notation?

A way to write numbers (usualy big numbers)\nImagine number 480,000,000\nIt is 4,8 * 100,000,000\nYou can write it as 4,8*10^8 or simply 4,8E8\n3 452 000 000= 3,452E9\n\nIt is very easy to multiply these numbers

People use alpha and omega for the unknowns. \nThey are letters of the greek alphabet.\nIn science they are used as constants.\nIn religion they are used to represent God.

The Edifier has it right, but darned if I can follow the notation. You really need to see this written out like a textbook to understand what's going on.\n\nClick the link below in "sources" to see the answer hosted at my website www.calculus-help.com. Right now, Yahoo! answers, as far as I can tell, doesn't allow graphics, which makes it tricky to answer ANY math questions.\n\nPlease don't post math answers, guys, if the poster knows the answer but can't get there, and you get something completely different.

It means power of 10 (it's a shorthand for scientific notation).\n\nSo your equation is:\n\n(1*10^-230)*e^(0.2682*x)\n\nWhere lower case e is the mathematical constant e (2.718...).

Oh my, that's amazing!\nHearts hearts to math and numbers.\nIsn't that what the sigma notation is all about?

It means "to the power of". Used for indices \n\neg. 4^5 is 4 to the power of 5

Function notation--which confuses a lot of people but it isn't that complicated--is a shorthand way of expressing formulas in mathematics (perhaps especially in algebra).\n\nSuppose, for example, that I have a formula for something.  Let's just use something silly, like the number of playing cards spread out on the table is equal to 52 times the number of decks that I opened.  So my formula is 52x.\n\nBut now think about how I use this.  "If I have one deck opened, replace the x with 1."  "If I opened two decks, replace the x with 2."  And so forth.  What is a quick mathematical way of saying that this is how the formula works?  Function notation.  I would simply say\nf(x) = 52x\nThe "f(x)" means "I have a function whose variable is x, and if you want to use the formula, then put your number in place of x in the following formula."  All of that is packed into "f(x)."\n\nAnd I can show the results as well:\nf(x) = 52x\nf(1) = 52(1) = 52\nf(2) = 52(2) = 104\nf(3) = 52(3) = 156\nAnd so forth.  That is all function notation is doing--it is giving us a quick way to show what variable to replace with values--and to show the results that are obtained when I do replace that variable with a value.

Every time that we move the decimal point to the left, we are dividing a number by 10. we can make up for this by decreasing the power of the exponent by 1.\n\nEvery time that we move the decimal point to the right, we are multiplying a number by 10. we can make up for this by increasing the power of the exponent.\n\n\n.0035 x 10^15 = 3.5 x 10^12\n.002 x 10^17 = 2 x 10^14\n\n7000 x 10^33 = 7 x 10^36\n\nWhen multiplying two scientific notation numbers, like\n\n(a x 10^b) * (c x 10^d)\n\nmultiply a and c, and add b and d. Use the sum as the exponent of the product.\n\nSo:\n\n(3.5 x 10^12) * (2 x 10^14) = 7 x 10^26\n\nNow we can divide.\n\nWhen dividing two scientific notation numbers, like\n\n(a x 10^b) / (c x 10^d)\n\ndivide a by  c, and subtract d from b. Use the difference as the exponent of the product.\n\nSo:\n\n(7 x 10^26) / (7 x 10^36) = 1 x 10^(-10)

Brackets, Orders, Division, Multiplication, Addition, Subtraction.\nIn some countries its BEDMAS, where E is exponents.

Note: the symbol * means multiplication\n\n1/(3z+5)(2z-7)\n============\n(3z+5)(2z-7) is a short notation for (3*z+5)*(2*z-7)\n\nThis is exactly equivalent to (3*z)*(2*z-7) +(5)*(2*z-7)\nThis is exactly equivalent to 3*z*2*z +3*z*(-7) +5*2*z +5*(-7)\n\nnow lets reorganize all that:\n 3*2*z*z -3*7*z +5*2*z -5*7\nso in the end we get\n 6*z*z - 21*z +10*z -35\nwe then sum the z\n 6*z*z -11*z-35\n\nor in a more compact notation: 6z^2-11z-35\n\n2/ (2-y)(4-y)\n==========\nThis means (2-y)*(4-y)\nyou do like we did in 1/ and you get  y^2-6y+8

[O] is the symbol for the concentration of oxygen in the particular substance. So you would be detecting not only the presence of oxygen, but also how much is present.\nThis symbol is also used for 'oxygen radical' or an unpaired oxygen atom.

The notation 's', 'p', 'd', and 'f' originate from a now-discredited system of categorizing spectral lines.\n\ns= sharp\np= principal\nd= diffuse\nf= fundamental

Its alt+3, and FYI Alt and a number is a way of printing orginal symbols from ASCII text, (first printer data kinda thing)

Ah they are Common operator notation, we use it to to express mathematical sequences using tokens.\n\nPostfix and prefix are mainly used for computer programming, that is how the computer thinks when doing operational sequences of numbers. We use postfix and prefix to do lexical analysis as well. Take a look at the webpage and you will know what I mean:)\n\nTake a look at Wikipedia they have a great article

Good question. \n\nIt's just notation. Just like why do we show potential energy by U? Why do we show density by "rho"?
