Math question: What is the sum of all the odd integers between 1 and 9899?

To find the sum of odd integers, we use the arithmetic series formula Sn = n/2(2a + (n-1)d), where Sn represents the sum of the series, a is the first term, d is the common difference, and n is the number of terms. In this case, we have a = 1 (first odd number), d = 2 (the difference between consecutive odd numbers), and the last odd term is 9899. To find n, we need to solve for n in the equation 1 + (n-1)2 = 9899. Solving for n, we get: n = (9899-1)/2 + 1 = 4950. Using the formula Sn = 4950/2(2(1) + (4950-1)(2)), simplifying it further, we have Sn = 2475(2 + 9898), which gives Sn = 24,487,625. Therefore, the sum of all odd integers between 1 and 9899 is 24,487,625.

Math question: What is the sum of the digits in the number 9899 after it is multiplied by 7 and then divided by 3?

To find the solution, we first multiply 9899 by 7, which gives us 69293. Next, we divide 69293 by 3, yielding 23097.6667. Since we are dealing with numbers, we disregard the decimal part, resulting in 23097. Now, to get the sum of the digits in 23097, we add 2+3+0+9+7, giving a final answer of 21. Thus, the sum of the digits is 21.

What is the square root of the sum of the digits of the number 9899 multiplied by the difference of the digits of the number when increased by their product minus the sum of the digits?

To find the square root of the sum of the digits of 9899, we first calculate it: 9 + 8 + 9 + 9 = 35. The difference of the digits is: 9 - 8 - 9 - 9 = -17. When we increase this by their product (9*8*9*9 = 5832) and subtract the sum of the digits (35), we get -17 + 5832 - 35 = 5780. Finally, the square root of 5780 is approximately 75.9345.
