Math question: What is the sum of the digits of the number 1087?

To find the sum of the digits, we add the individual digits together. In this case, 1 + 0 + 8 + 7 equals 16.

Math Question: What is the value of 1087 squared, divided by the square root of 1087, multiplied by the sum of its digits, subtracted by the greatest prime number less than 1087, and then added to the square root of the sum of all numbers from 1 to 1087?

Let's solve the question step by step. First, finding 1087 squared equals 1176769. The square root of 1087 is approximately 32.949. The sum of its digits (1 + 0 + 8 + 7) is 16. The greatest prime number less than 1087 is 1087 itself. Now, we have the equation: (1176769 / 32.949) × 16 - 1087 + √((1 + 2 + 3 + ... + 1087)). Let's calculate further. 1176769 divided by 32.949 equals 35689.888, approximately. Multiplying this by 16 gives us 570238.208. Subtracting 1087 becomes 569151.208. Now, let's find the sum of all numbers from 1 to 1087. Using the formula n(n+1)/2, where n is 1087, we get 591657 (rounded). Taking the square root gives us approximately 768.923. Adding the square root of the sum to our previous result, we have 569151.208 + 768.923, which equals 569920.131. So, the answer is 569920.131.

Math question: What is the sum of the digits in the number 1087?

To find the sum of digits in 1087, we add the value of each digit together. Starting from the left, the digit 1 has a value of 1, followed by 0 with a value of 0, then 8 with a value of 8, and finally 7 with a value of 7. Adding these together (1 + 0 + 8 + 7) gives us a sum of 16. Hence, the sum of digits in the number 1087 is 16.
