Question: What is the remainder when the number 2042 is divided by 7?

To find the remainder when 2042 is divided by 7, we proceed as follows: The largest multiple of 7 that is less than or equal to 2042 is 2041 (7 * 292). Therefore, subtracting 2041 from 2042 leaves us with a remainder of 1. Thus, when dividing 2042 by 7, the remainder is 1.

The math question for the number 2042: What is the sum of the digits in the number 2042 when the last digit is subtracted from the sum of the other three digits?

To find the sum of the digits in 2042, we first sum the individual digits: 2 + 0 + 4 = 6. Then, we subtract the last digit, 2, from this sum: 6 - 2 = 4. Therefore, the answer is 4.

Math question: What is the product of 34 and 60 when added to the quotient of the square of 17 and the difference between 50 and the sum of 26 and 7?

To find the product, first calculate the square of 17, which is 289. Then find the sum of 26 and 7, which is 33. Next, subtract 33 from 50, resulting in 17. Now multiply 34 by 60, obtaining 2040. Finally, divide 289 by 17 to get 17. The answer is obtained by adding 2040 with 17, giving us 2057
