Math question: What is the sum of the digits in the number 207?

To find the sum of the digits in the number 207, we add the individual digits together. We have 2 + 0 + 7 = 9. So, the sum of the digits in the number 207 is 9. Explanation: The number 207 has three digits: 2, 0, and 7. The sum of these digits is obtained by adding them together. Thus, 2 + 0 + 7 equals 9. Hence, the sum of the digits in the number 207 is 9. This concept can be applied to any number by breaking it down into its individual digits and performing the addition process accordingly.

Math question: What is the sum of all numbers from 1 to 207 that are divisible by either 3 or 7?

To find the sum of numbers divisible by 3 or 7 up to 207, we can use the principle of inclusion-exclusion and find the sum of numbers divisible by 3, the sum of numbers divisible by 7, and then subtract the sum of numbers divisible by both 3 and 7. The sum of numbers divisible by 3 up to 207 can be found using the arithmetic series formula: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. The first term divisible by 3 is 3, the last term divisible by 3 is 207 - (207 % 3) = 207 - 0 = 207. The number of terms can be found using the formula: n = (l - a) / d + 1, where d is the common difference. So, n = (207 - 3) / 3 + 1 = 69. Using the formula, the sum of numbers divisible by 3 is: S3 = (69/2)(3 + 207) = 35(210) = 7350. Similarly, the sum of numbers divisible by 7 can be found: The first term divisible by 7 is 7, and the last term divisible by 7 is 207 - (207 % 7) = 207 - 6 = 201. So, n = (201 - 7) / 7 + 1 = 29. S7 = (29/2)(7 + 201) = 15(208) = 3120. Now, we need to find the sum of numbers divisible by both 3 and 7. The first term divisible by both 3 and 7 is their least common multiple, which is 21. The last term divisible by both 3 and 7 is 207 - (207 % 21) = 207 - 9 = 198. So, n = (198 - 21) / 21 + 1 = 9. S21 = (9/2)(21 + 198) = 135(219) = 29565. Finally, subtracting the sum of numbers divisible by both 3 and 7 from the sum of numbers divisible by 3 and 7: Sum = S3 + S7 - S21 = 7350 + 3120 - 29565 = -19095. Therefore, the sum of all numbers from 1 to 207 divisible by either 3 or 7 is -19095.

Math question: What is the sum of 207 and its double, divided by their difference, all squared, and then subtracted by the quotient of 207 and its square root?

To solve this, we begin by calculating 207 doubled, which is 414. The sum of 207 and 414 is 621. The difference between these two numbers is 207. Dividing 621 by 207 yields 3. We square 3, which gives us 9. Lastly, the square root of 207 is approximately 14.387. When we divide 207 by 14.387, we get 14.3805. Now we can combine all calculations: 9 - 14.3805, which equals -5.3805. Therefore, the answer to the math question is approximately -5.3805.
