What is another name for the decimal system?
99174
i think the answer is "positional" however that is only one word. you sure its two words?

Do you mean what are the English names?\n\n0.1 = tenths\n0.01 = hundredths\n0.001 = thousandths\n0.0001 = ten thousandths\n0.00001 = hundred thousandths\n0.000001 = millionths\n0.0000001 = ten millionths\n0.00000001 = hundred millionths\n0.000000001 = billionths\n0.0000000001 = ten billionths\n0.00000000001 = hundred billionths\n0.000000000001 = trillionths\n0.0000000000001 = ten trillionths\n0.00000000000001 = hundred trillionths\n0.000000000000001 = quadrillionths\n...\n0.000000000000000001 = quintillionths (10^-18)\n...\n10^-21 = sextillionths\n10^-24 = septillionths\n10^-27 = octillionths\n10^-30 = nonillionths\n10^-33 = decillionths\n10^-39 = undecillionths\n10^-42 = duodecillionths\n10^-45 = tredecillionths\n10^-48 = quattuordecillionths\n10^-51 = quindecillionths (quinquadecillionths)\n10^-54 = sexdecillionths (sedecillionths)\n10^-57 = septendecillionths\n10^-60 = octodecillionths\n10^-63 = novemdecillionths (novendecillionths)\n10^-66 = vigintillionths \n10^-100 = googolths\n10^-303 = centillionths\n10^-googol = googolplexths  :-)\n10^-infinity = zeroths :-)\n\nNotice that each decimal place value name is similar to a whole number place name, except that these decimal names all end in ths.

Binary numbers use only one (1) and zero (0). \n\n10 in binary is 2 in decimal.\n11 in binary is 3 in decimal.\n110 in binary is 6 in decimal.\n\n(Decimal numbers are normal numbers.)

Decimal is the normal way to write numbers: .00002\nScientific notation is 2x10^-5\nTo do this just move the decimal over to the right (-) an count the number of 0's you pass and put 10 to that power.  If you move the decimal to the left then the power is positive.\n\nWhy do scientist do this?  In our solar system there are some very big numbers like 360,000,000,000,000.  It is easier to just write 3.6x10^14.  There are also numbers that are very small such as in atoms.  Hope this helps.

Yiu would first decide how many decimal places you are going to consider.  The usual is 3.  Then work it from there...;

This is 8 bit binary system.\nand u know, there are only two possibilities for a switch (on/off or 0/1).\nin binary syatem, as i have to take 10101000, to convert into decimal.\nfrom right to left:\n0*2^0 + 0*2^1 + 0*2^2 + 1*2^3 + 0*2^4 + 1*2^5 + 0*2^6 + 1*2^7 = 168 (it is the decimal form).\n\nsimilarly as we take 10110001\n\nthen its decimal is :\nfrom right to left : and increase pawer of 2 from 0 step 1.\n1*2^0 + 0*2^1 + 0*2^2 + 0*2^3 + 1*2^4 + 1*2^5 + 0*2^6 + 1*2^7 =  177

Zero is in the Hundreds position. \n\nTwo is in the Thousands, \nOne is in the Tens position,\nNine is in the Ones position.\n\nOnce you move to the right of the decimal, it is:\n\nFour in the Tenths position,\nSix  in the Hundredths position,\nand Three is in the Thousandths position.

I'm not sure if you mean decimal or just number\nif it is decimal then it would be:\n\n7.420\n\nif just number then: 7420

If decimals are allowed, then (73+7)*.3 is a nice solution :)\n\nIf not, then the only solution I could find is (3+(3/7))*7\n\nEDIT : As for the initial question, absolutely! Math is my favorite subject, even in college. I won several contests in high-school, and love any sort of math puzzles. If you know of any more, please e-mail me :)\n\nSubmarinerdave : Heh. That's what I thought of as well, my sister has a 24 contest at her school two years ago :) A similar but more challenging game is the 2006 math game, where you try to make numbers from 1 to 100 using the digits 2,0,0, and 6. Link below.

It's so that the person you are talking to knows what you are talking about.\n\nWhat would the alternative be? "Twelve and seven hundred and eighty-nine thousandths?" That's a bit cumbersome.\n\nThe decimal point *creates* a division between the numbers, so we need to replicate that division by saying "point." It just makes sense.

decimal: 1 + 1 = 2 (vase 10)\nbinary: 1 + 1 = 10 (base 2)\nphilosophically: they say 11, but i would say endless (case in point Hewlett and Packard or Bill Gates and Stevel Balmer or Steve Jobs and Wozniak)

Depends what Base you are using.\n\nIn decimal it is 1234602335680234\n\nIn Hexadecimal it is 0x123463677ABD69AC\n\nI'll leave other bases as an exercise for the student...

The 1 is in the 1000ths place:\n\nThere's no "1s" After the decimal. AFTER the decimal, it goes 10ths, 100ths, 1000ths, etc.\n\nUse this key for more problems you might have:\n1000s, 100s, 10s, 1s . 10ths, 100ths, 1000ths, etc

binary 11 is 3 decimal

To be in scientific notation, the decimal point which is now at the right end of the number must be moved to the left until it is after the first non-zero digit.  That takes five place moves for the decimal point.  This number of moves, 5, becomes the exponent of 10.  The extra zeros after the decimal point are dropped (unless the 200,000 is accurate to the ones place).  So your answer is 2 x 10^5.
