# What is the sum of the first 144 decimal digits of pi?

Pi to 144 decimal places is written thus:

3.14159265358979323846264338327950288419716939937510

58209749445923078164062862089986280348253421170679

82148086513282306647093844609550582231725359

The sum of these first 144 decimal digits (after the decimal point) is 666.

### If the sum of the digit is divisible by 3 the number is divisible by?

That means the number itself is divisible by three. the sum of the digits in 144, for example, is 9. 144 divided by 3 is 48. The sum of the digits in 21 is 3. 21 divided by 3 is 7.If the number is an even number and the sum of the digits is divisible by 3, the number is also divisible by 6. 144 is even and the sum of the digits is divisible…

### When you get two decimals how do you know where to put the decimal point in the product?

Count the numbers of digits after the decimal points (DP) in the two numbers. Add these numbers together. Calculate the product, including any trailing 0s. Place the DP so that the number of digits after the DP is the same as the sum of the digits after the DP (step 2). Thus, for 15.38 * 0.0045 The first number has 2 digits after the DP, the second has 4, so sum of digits after DP…

### What is the sum of all possible four digit numbers using the digits 4068?

If you accept 4-digit numbers with 'zero' as the first digit, then there are 24 possibilities, and their sum is 119,988 . -- If the first digit can't be a 'zero', then there are 18 possibilities, and their sum is 115,992 . Note: I didn't repeat any digits. -- If you allow repeated digits, and accept leading zeros, then there are 256 possibilities, and their sum is 1,279,872. -- If you allow repeated digits…

### How is multiplying two decimals similar from multiplying one decimal by a whole number?

You simply multiply the two numbers together ignoring the decimal point. You then count the number of decimal places in each of the multiplicands and add them together. In the product, you put the decimal point so that there as many digits after the decimal point as that sum. For example, to multiply 2.63 by 3.271 263 * 3271 = 860273. There are 2 digits after the decimal point in the first multiplicand and 3…

### How many whole numbers between 100 and 300 whose digits equal 11?

I assume you mean the sum of the digits. If the first digit is 1, the other two digits have to sum 10. There are 9 different possibilities for this, from 1 + 9 to 9 + 1. If the first digit is 2, the other two digits have to sum 9. There are 10 different possibilities for this, 0 + 9 to 9 + 0. Adding it all up, it seems there are 19…

### How do you add decimals together?

to add decimals: -line up the decimal points -then starting at the farthest place to the right, add the decimal in each place -if the sum of the digits in a place are greater than nine,regroup the number to the place to its left. -check the sum by writing each decimal as an equivalent fraction and then adding these numbers or mixed numbers.

### When adding 85.4 plus 097 plus 1.30 the number of decimal places in your answer should be?

Assuming you meant 85.4 + 0.97 + 1.30, the correct number of decimal places should be 1, that is, only one digit after the decimal point. When determining the number of significant digits for purposes of addition, you round it off to the least precise of the numbers - the one with the fewest digits to the right of the decimal point. If you are asking how many total digits the answer should have…

### Is 144 divisible by 2 3 4 5 6 9 or 10?

144 is divisible by 2, 3, 4, 6, 9 and not divisible by 5 or 10. Divisible by 2 The whole number is divisible by 2 if the number is even which is shown by the last digit being divisible by 2. The last digit of 144 is 4 and 4 is divisible by 2, thus 144 is divisible by 2. Divisible by 3 The number is divisible by 3 if the sum of its…

### How do you line up decimals when you subtract or add?

To add decimal numbers: Put the numbers in a vertical column, aligning the decimal points Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left. Place the decimal point in the answer directly below the decimal points in the terms. To subtract decimal numbers: Put the numbers in a vertical column, aligning the decimal…

### What is a digit sum of a number?

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…

### What is the smallest positive multiple of 13 for which the sum of its digits is prime?

Start with the smallest multiple of 13 and continue with the next smallest until finding one that fits the specifications. 13, sum of digits is 1 + 3 = 4 which is not prime 26, sum of digits is 2 + 6 = 8 which is not prime 39, sum of digits is 3 + 9 = 12 which is not prime 52, sum of digits is 5 + 2 = 7 which is prime…

### Write a c program to find the sum of the five digits of a number?

To determine the value of the least-significant digit in a number, you divide by the base and take the remainder. To get the next digit, divide by the base and repeat. The following function will sum the digits of any integer (the length does not matter): int sum_digits (int num, int base=10) { // assume decimal notation by default int sum = 0; while (num) { sum += num%base; // add the least-significant digit num…
