"numeral" and as Webster defines: a symbol or set of symbols used to represent a number

I GOT THIS ANSWER!! When you write it as a roman numeral!!

The answer is 23475.\n\nLet's look at how I got there:\n\n\nThe first digit is a prime number:  2,3,5,7\n\nOne is not a prime, so anything starting with 1 is not actually an option.  There are two valid numbers, but one of them has repeating digits.\n\nGood.  That narrows it down a lot.\n\nThe third digit is twice the first digit:  Following from the numbers possible for the first digit, it's 4,6,10,or 14.  It obviously cannot be the last 2 since they are two digits.  That means it is either 4 or 6, and the first digit is 2 or 3.\n\nSo far we have\n2x4xx or\n3x6xx\n\nThe fourth digit is the third digit plus 3.  That's easy.  We now have\n2x47x or\n3x69x\n\nThe fifth digit is the difference between the first digit and the fourth digit.  7-2=5 and  9-3=6  We now have\n\n2x475 or\n3x696\n\nWait!  The second number has a repeated digit, 6.  It thus cannot be the number.\n\nLet's go on with option 1.  The second digit is the fifth digit minus the first digit.  5-2=3\n\nThe number is 23475.\n\n\nHope this helps.

Arrays are convenient ways to summarize numbers without writing out additional details.  For example, if I had two equations:\n\n3x + 2y = 5\n7x + 91y = 80\n\nthen an array would have just the numbers\n\n3 2 5\n7 91 80\n\nHow third graders will use this- I have no idea.

Grappling with the axiomatic logic is not suitable for most of\nus and these readings are difficult.  Let me attempt an inadequate simplifi-\ncation.  I would say a number "belongs to a concept" and is an\nextension of that concept and then statements about numbers correspond to\n"identities of concept".\n\nIn the sense of counting, one apple and one orange represent identical\nconcepts even if apples are not oranges, so we write 1 = 1.  Now 1 + 1 or\nfor that matter 1 + 1 + 1 + 1 + 1 + 1 (repeating)  are represented in the\nsense of identity by other symbols which, if arabic numerals are used, we\nwrite as 2 or 5.  The symbols are just compact notation for representation\nof an identical "concept".  I would say that number is not anything\nphysical nor is it subjective.  This may not be very satisfying but deep\nphilosophical questions about numbers may always remain unanswered in very\nsatisfying ways.

its impossible because there needs to be either one less sign or one more number look:\n\nin a the order:\n2 * 4 - 6 + 8 /\n              ^there is an extra sign!!

I think the term for these prefixes is ordinal.  Depending on the capabilities of your word-processing software, printer, preference of your professor, etc., you can write them beside the number (1st, 2nd, 3rd, 4th, etc.) or you can super-script them (I assume that's what you mean by "exponentially").  I've never seen them used with roman numerals.

Mode is most occuring. I always remember it because like M for most and O for occuring. \n1 3 4 4 4 4 4 5 6 6 6 \n \n4 would be the mode\n\n\nMedian is like middle number. median.. middle. they just kinda go together. you line them up in order then cross the end ones off until there is only one left. if there are two of them left then add them up and divide by two.\n \n2 3 4 5 6 7 8\n \nfive would be the median\n\n\nMean is average. i always remember it by ME Average? haha kind of doesnt make sense but hey it works for me. thats when you add all the numbers up and divide the sum by how many numbers there are \n\n1 2 3 4 5 6 \n\nso 1+2+3+4+5+6 = 21 / 6 =  3.5\n\nso the mean is 3.5

in many cases, you need innovative thinking.. Consider this:\n\n250*844 = 250*(4*411) = (250*4)*411 = 1000*411 = 411000\n251*844 = (250+1)*844 = 250*844 + 1*844 = 411000 + 844 = 411844\n\n37*123 = 37*3*41 = 111*41 = (100+10+1)*41 = 4100+410+41 = 4551\n\nsometimes, do not oversimplify...\n105*598 = (100+5)(600-2) = 100*600 - 100*2 + 5*600 - 5*2 = 60000 - 200 + 3000 -10 = 62890 (not good)\n\n105*598 = 105*(600-2) = 63000 - 210 = 62890 (better)\n\nThe key is, you have gotta practice a lot.\nFor example, when I see 111*41, I wrrite down in a peice of paper like this:\n\n(* = space)\n41**\n*41*\n**41\n----\n4554

You need to round off the number to 4 digits and use the proper exponent to reflect the entire number:\n\n1.496 x 10^11  Your first answer is correct.

312211.\n\nThe first number is 1.  The second number is "one 1", how the previous number was constituted.  The third number is "two 1s", or how the second number was constituted.  The fourth number is "one 2, one 1", or how the previous number was constituted.  The fifth number is "one 1, one 2, two 1s", or how the number was constituted.  The fifth number is 111221, so the sixth number should tell you how it was constituted: three 1s, two 2s, one 1.

For starters, S can only be a 1 or a 2 as any other number would have made the P bigger than 10, and that does not work.\nBut then, since 4 A is a number that ends with S, it cannot be 1, as S needs to be even, so S is 2.\n2oda+2oda+2oda+2oda=pop2\nWe can also look at the "p": it can only be 8 or 9, depending if the 4 "o" create a carry or not.  But we know that 4 "o" create a number that ends with a "o" unless the 4 "d" also create a carry.\nZero do that (without the carry) 3 would create a number ending with 2 but ending with 3 if there is a carry from the sum of "d", 4 would make un number ending by 6, so would need a carry of 8 to get to 24, but then we would have 2 to carry over the toal of "s" and that would make "p" 10 which is not acceptable, so "o" is either zero or 3 with a carry of one from the total of "d". But if there is no carry (if "o" is zero) then "p" has to be 8, and "d" would have to be 2, but 2 is already "s"; so "o" has to be 3, and "p" is 9.\n\n23da+23da+23da+23da=9392.\n\nand "d" has to be 4 and "a" is 8.\n\n2348+2348+2348+2348=9392

pythagoreans called it a "triangular number" as it is the sum of the first three numbers 6= 1+2+3;\nthis can be represented in a triangular shape:\n\nX\nXX\nXXX\n\nThat's all.

I suppose my best answer would be any system that uses a single 'symbol' to represent a numerical value.\n\nThe 'digit' system most people are accustomed to is "base 10" where the digits range from '0' to '9'.\n\nIn the case of 'hexadecimal', the digit system includes not only the digits from '0' to '9', but also the letters 'A' through 'F', which represent the numerical values 10 through 15 (in base 10), but they are represented by a single digit.\n\nA digit system, in my humble opinion, is one that maps a numerical value (which may require one or more symbols to represent it) to a single symbol that represents that value.

1, 2, 3, 4, 5, 6, 7, 8, 9, ect.\nHow old r u??? this stuff is EASY.....gee whiz I'm in 6th grade and I know this stuff

here are some examples\n\n5,6,2,3\n\nMedian - Put in accending order (2,3,5,6) Find the middle number, or in this case the middle two (3 & 5) and divide by two. 3/5\n\nMode - Does not exist here. What ever number or numbers is repeated the most.\n\nMean - 5+6+2+3=16  16/4(amount of numbers) = 4\n\nTry to do it in the order i did. I always get confused with the Mean and Mode. Just remember that Median sounds like Middle. Mode reminds you of functions and stuff. So just think of repetition. and Mean is left over.

very good question: "number" is the quantity in itself: it's "how much you have" of something.\n\nFigures are signs that you use to represent that quantity.\n\nThe number is an objective and absolute entity; the figures you use to represent the number may depend.\n\nfor exemple, if you want to describe the number of x's in the following:\n\nx  x  x  x  x  x  x  x  x  x\n\naccording to the number system you use, the same number can be written 10 (base 10) or A (base 16) or 1010 (base 2). \n\nSo the figures change, but the number is always the same.\n\n---\nAnother thing to think about: consider even numbers.\nThe correct definition of an even number is that it is divisible in two equal parts; if you base your definition on figures, saying that an even number is a number which ends by 0,2,4,6 or 8, you're just referring to base 10 and are not telling the truth relating to other bases:\n\nfor exemple, the number four is written 11 in base 3, but it is still an even number!\nThe same for each odd base: the even number consecutive to the base is always written 11 in that base...\n\nSo to be even is an intrinsic quality of the number; to be written "evenly" according to base 10 criteria is not.
