Math Question: Find the sum of all even numbers between 1000 and 2000, excluding multiples of 5.

To find the sum of the even numbers between 1000 and 2000 (excluding multiples of 5), we need to determine how many even numbers are in this range and their sum. There are 501 even numbers between 1000 and 2000. Next, we calculate the sum using the arithmetic series formula: Sn = (n/2)(a1 + an). The first term (a1) is 1002, and the last term (an) is 1998. Substituting these values, Sn = (501/2)(1002 + 1998) = 251(3000) = 753,000. Thus, the sum of the even numbers between 1000 and 2000 (excluding multiples of 5) is 753,000.

Math question: What is the sum of the digits of 2303?

To find the sum of the digits of 2303, we first separate the digits: 2, 3, 0, and 3. We then add these digits together: 2 + 3 + 0 + 3 = 8. Therefore, the sum of the digits of 2303 is 8.

Math Question: What is the sum of the digits of the number 2303 squared minus the cube root of 2303 multiplied by the square root of 2303, all rounded to the nearest whole number?

To find the answer, we first calculate 2303 squared, which equals 5,301,609. Then, we find the cube root of 2303, which is approximately 13.507. Next, we calculate the square root of 2303, which is approximately 47.981. Now, we multiply the cube root (13.507) by the square root (47.981), which gives us approximately 647.781. Subtracting this multiplication from 5,301,609 gives us 5,300,960. Finally, summing the digits of this result (5 + 3 + 0 + 0 + 9 + 6 + 0) yields 23. Therefore, the answer is 23.
