To find the digit sum of a number you plus the first 2 numbers together, example:the number 18, 18 is made up of 2 digits 1 and 8.If you add the 2 digits together you get a total of 9.So that is the digit sum of 18.But if you use a higher number like 66 then the method has a small change.First if you add the two digits together it becomes 12.But 12 isn't a single digit sum.So again the 2 digits have to be added together to make a single digit sum.1+2=3 so 3 is the single digit sum for the number 66.
A positive number is greater than a negative number. If a positive number is greater than another, the corresponding negative numbers are smaller. For example, since 4 > 3, -4 < -3. For two positive numbers: The number with more digits is greater. If they have the same number of digits, the number with the greater first digit is greater. If they are equal, look at the second digit, which will decide which number is greater, and so forth, up to the last digit. For example, 12500 is greater than 12480: they have the same number of digits, the first two digits are the same, but the third digit is the tie-breaker. For numbers with decimals, first apply the rules above for the whole part. If they are equal, check the first digit after the decimal point, then the second, etc., until you find a "tie-breaker". For example, 0.2522 is more than 0.2517. Once again, the first two digits are the same, the third is the tiebreaker.
24 this is a factorial if you come across a question like this again count how many then multiply down from that number. 4x3x2x1 for four 5x4x3x2x1 for five and so on
There should be 125 combinations, but if you can only use the numbers once for each 3 digit number, then it should be 120. It's 125 because if the digits could be used more than once for each number then its the number on possible numbers (so there's 5 in this case, 2, 3, 5, 8, and 9) to the power of how big the digit is (in this case it's 3) It's 120 because if the digits could only be used once in each number then the combinations would be the number of possible numbers (again, 5) factorial, so 5!

No; the only condition for qualyfing as an irrational number is that the same pattern of digits doesn't repeat over and over again, as it does with a rational number. For example, 8/7 is a rational number; the decimal expansion is 1.142857 142857 142857 ... As you see, the same pattern of digits repeats over and over. The number may start with different digits, but if after a while the same pattern repeats again and again, the number is rational.The following number is irrational: 0.101001000100001000001 ... The pattern doesn't repeat, because a zero is added every time. And, in this example, the decimal expansion doesn't contain any digits other than 0 and 1.
There is no way to know how many significant digits are in 33000. If you are forced to choose then there are 2 significant digits but, again, there is really no way to tell. If the count of significant digits is important, the number should be expressed in scientific notation.
Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.
The number before the decimal point is written in word form without suing "and". Next an "and is used where the decimal point appears. Then the number after the decimal point is written out in word form (again, without using "and"). Finally, the inverse power of ten is written and this is based on the number of digits after the decimal point.For 1 digit: tenths 2 digits: hundredths 3 digits: thousandths 4 digits: ten thousandths 5 digits: hundred thousandths 6 digits: millionths and so on.
Yes, freeze it again.
The meaning of digits in a bank account number vary by country and again by bank. In the US, there are two sets of numbers - the bank routing number (whose length is 9 digits long and identifies the bank, a state, and potentially a branch) and the account number (whose length varies by bank and uniquely identifies the customer). For countries using SWIFT (equivalent to the US routing number), there are either 8 or 11 digits in the SWIFT code (which identifies the institution, the country, location, and the branch). The account numbers, again, vary by bank and uniquely identify the customer (in some cases, they also identify the bank/sales representative). For countries using IBAN (International Bank Account Number), the entire number incorporates the bank and customer information. The number of digits varies by country and the specific digits have different meanings by country. A link summarizing the IBAN and SWIFT standards are included at the end of this answer.
Well, honey, the largest 12-digit number with repeated digits allowed is 9,999,999,999,999. I mean, unless you want to get fancy and start throwing in letters or emojis, but I doubt that's what you're looking for. So there you have it, the biggest 12-digit number you can get with the same digit repeated over and over again.
Ther is at least one too many digits in your serial number. Please recheck and ask again
A prime number is only divisible by 1 and itself. If all three digits have to be used then any number formed from them is divisible by 9 as the sum of the digits = 9. Thus no prime number can be formed. If only two of the three digits are used then it cannot end in 0 or 8 as it would be divisible by 2. This only leaves 81 where the digits again total 9 and thus is divisible by 9. None of the single digits 0,1,8 are prime. 8 is an even number. 1 is classed as unity, 0 is zero.
The following function will sum the digits in any positive number. unsigned int sum_digits(unsigned int num, unsigned int base=10) { sum=0; if(base>1) // base must be 2 or higher { while(num) { sum+=num%base; // add least significant digit to sum num/=base; // shift right by base } } return(sum); }
