Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

What is CXCLV in Hindu-Arabic numerals?
The numeral CXCLV does not comply with the rules which govern Roman numerals so it isn't a real numeral at all. C = 100 and XC = 90 but L = 50 and V = 5. If you add these values together you reach a total of 245 which should correctly be written as CCXLV (100 + 100 + 40 + 5)
Write 1000000000000000000 in words?
The number 1,000,000,000,000,000,000 can be written as "one quintillion" in words. In the short scale system, which is commonly used in the US and modern English-speaking countries, each group of three zeros is represented by a new term (thousand, million, billion, trillion, quadrillion, quintillion, and so on).
What prime numbers are between 6 and 10?
The prime numbers between 6 and 10 are 7. Prime numbers are integers greater than 1 that have no divisors other than 1 and themselves. In this case, 7 is the only prime number within the specified range.
Why does the Lebesgue number not exist in a open and bounded set?
Because there are too many possibilities for the open covering. For a compact set, any family of open sets that covers can be replaced by a finite subfamily of open sets that still covers. Hence the open sets can't be too small.
Without compactness, the open sets can be quite small. For example, the infinite family of intervals (1/(n+1), 1/(n-1)) covers the open bounded set (0,1). (Here n is any integer larger than 1.) No subfamily will cover (0,1), and since the sets have radius going to zero, the Lebesgue number would also have to be zero.
How would you spell 4531985219092?
Well, honey, that's a whole lot of numbers to spell out! But if you want it in words, it would be: four trillion, five hundred thirty-one billion, nine hundred eighty-five million, two hundred nineteen thousand, ninety-two. Hope you have a big piece of paper to write that down!
How do you write 4.20 percent in word form?
Well, honey, you write 4.20 percent as "four point two zero percent." It's as simple as that. Just make sure you don't accidentally write "four point two zero percent" on your tax forms, unless you want a visit from the IRS.
To express 0.030 as a fraction, we need to consider the decimal places. Since 0.030 has three decimal places, we can write it as 30/1000. To simplify this fraction, we can divide both the numerator and denominator by 10, resulting in 3/100. Therefore, 0.030 as a fraction is 3/100.
Oh, dude, 2400000 in words is like, two million four hundred thousand. So, if you're ever in a super fancy situation where you have to spell out this big ol' number, now you know how to impress everyone with your wordy skills.
How do you write 1.2 in words?
To write 1.2 in words, you would write "one point two." In this case, "one" represents the whole number part (1) and "two" represents the decimal part (0.2). This format is commonly used to represent decimal numbers in word form.
What is 10 to the power of 120th power called?
"10 to the power of 120th power" is gibberish. It would need a third number to mean anything at all.
The first answer by ProfBot is wrong. 10^(10^120) is not a googolplex, nor is a googol 10^(10^100). A googol is 10^100 and a googolplex is 10^(10^100).
What is an equivalent decimal for the number 3.5?
3.50 is equal but it implies a greater degree of precision.
What is 101 101 in binary numbers?
Oh, dude, 101 101 in binary is 45 in decimal. It's like converting a secret code into regular numbers, but way less exciting. So, yeah, 101 101 is just 45 in binary - not as cool as it sounds.
How Express 840 as the product of prime numbers?
Oh, what a happy little question! Let's break down the number 840 into its prime factors. We start by dividing 840 by the smallest prime number, which is 2. Repeat this process until you cannot divide anymore, and you'll find that 840 can be expressed as 2 x 2 x 2 x 3 x 5 x 7. Just like that, you've decomposed 840 into its prime factors, creating a beautiful mathematical masterpiece!
How do you write 14 million in numbers?
Oh, that's a happy little question! To write 14 million in numbers, you simply write the number 14 followed by six zeros. It's like painting a beautiful number landscape on your canvas of math. Just remember to add those zeros for a truly magnificent numerical masterpiece.
What is the composite number between 60 and 80?
Oh, what a happy little question! Let's take a moment to appreciate the beauty of numbers. The composite number between 60 and 80 is 64. It's made up of factors other than just 1 and itself, like 2, 4, 8, 16, and 32. Just like in painting, numbers can come together to create something truly wonderful.
MDCCCCV in roman numerals was the ancient way to represent the number 1905. Modern rules do not allow a character to be written more than three times consecutively, so the number 1905 would be written in the modern age as MCMV.
0.909 can be represented as a fraction by first putting it over 1,000
909/1000 = .909
As it turns out, this fraction (909 / 1000) cannot be simplified anymore, so this is the answer.
Do larger numbers have more factors than smaller numbers?
Generally yes, but not in all cases. The largest prime number has over 22 million digits but only two factors whereas 60 has six times as many factors.
What is number word for 100000000000000000000000000?
Ah, that's a big number! The word for 100,000,000,000,000,000,000,000 is "one septillion." Just imagine all the happy little zeros dancing together in harmony, creating a beautiful number that stretches as far as the eye can see.
