What is the sum of the first 83 even numbers minus the first 42 odd numbers, divided by 7, and subtracted by the square root of 166?

To find the sum of the first 83 even numbers, use the formula (n/2)(first term + last term) where the last term is 83*2. This gives us (83/2)(2 + 83*2) = 83(166) = 13738. Similarly, the sum of the first 42 odd numbers is (42/2)(1+41*2) = 42(42) = 1764. Next, divide the difference between these sums by 7: (13738 - 1764) / 7 = 16374 / 7 = 2339.14. Finally, subtract the square root of 166: 2339.14 - √166 ≈ 2339.14 - 12.884 = 2326.256. Therefore, the answer is approximately 2326.256.

Math Question: What is the value of 166 divided by 2, then multiplied by 3, subtracted by 10, and divided by 4, squared, and added to 10 times the square root of 166, rounded to the nearest whole number?

To solve this, we begin by dividing 166 by 2, resulting in 83. Next, we multiply this by 3, obtaining 249. Subsequently, we subtract 10, leaving us with 239. Now, dividing this by 4 gives 59.75. Squaring this value yields approximately 3570.0625. Lastly, adding 10 times the square root of 166 (317.369) to this squared value, we get approximately 3887.4315. When rounding this to the nearest whole number, we obtain 3887 as the final answer.

Math question: What is the sum of the digits of the number 166?

To find the sum of the digits, we add 1 + 6 + 6, which gives us 13.
