What is the sum of the digits when multiplying 1630 by its own reverse?

To find the reverse of 1630, we write it as 0361. Now, multiply 1630 by 0361, giving 591130. The sum of the digits in 591130 is 5+9+1+1+3+0 = 19.

Math question: What is the sum of the digits in the number 1630?

To find the sum of the digits in 1630, we add the individual digits together. Breaking it down, 1 + 6 + 3 + 0 equals 10. Therefore, the sum of the digits in the number 1630 is 10.

Math question: If 1630 is multiplied by the sum of its digits, divided by the square root of its penultimate digit, and then added to the product of its first and last digits, what is the result?

To find the result, let's break down the question. The sum of the digits in 1630 is 1+6+3+0=10. The square root of the penultimate digit (3) is √3 = ≈ 1.732. So, the first part is (1630 * 10) / 1.732 = ≈ 9430.874. The product of the first digit (1) and the last digit (0) is 1 * 0 = 0. Finally, adding the two parts, we get 9430.874 + 0 = 9430.874 as the result.
