Math question: If you subtract 457 from a number and then multiply the result by 5, add 642, divide by 3, and finally subtract 79, what is the resulting number?

To find the resulting number, we can break down the operations step by step. First, subtracting 457 from 2149 gives 1692. Next, multiplying 1692 by 5 yields 8460. Then, adding 642 to 8460 results in 9102. After that, dividing 9102 by 3 gives 3034. Finally, subtracting 79 from 3034 yields the resulting number: 2955. Therefore, the final answer is 2955.

Math question: Consider the four-digit number 2149. What is the sum of its digits?

To find the sum of the digits in the number 2149, we add the individual digits together: 2 + 1 + 4 + 9 = 16. Hence, the sum of the digits in the number 2149 is 16. Explanation: The given number 2149 has four digits: 2, 1, 4, and 9. In order to find the sum of these digits, we simply add them together. Thus, we have 2 + 1 + 4 + 9 = 16. Therefore, the sum of the digits in the number 2149 is 16. This fundamental concept of adding the individual digits in a number helps us analyze and understand numbers better. It also forms the basis for more complex mathematical operations and problem-solving.
