Question: What is the sum of the digits of the product when 1636 is multiplied by its reverse number?

To find the reverse of 1636, we get 6361. Multiplying 1636 by 6361 gives 10407296. Taking the sum of its digits, we get 1+0+4+0+7+2+9+6 = 29. Therefore, the sum of the digits of the product 1636 * 6361 is 29.

Math question: What is the sum of all the digits in the number 1636?

To find the sum of digits in 1636, we break down the number into its constituent digits: 1, 6, 3, and 6. Adding these digits together, we get 1+6+3+6 = 16. Therefore, the sum of digits in 1636 is 16.

Math Question: If you divide a number by 2, subtract 5, then multiply by 4, and finally add 250, the result is 1636. What is the original number?

Let's denote the original number as x. We can create an equation based on the given information as follows: ( x / 2 - 5 ) * 4 + 250 = 1636 To solve this equation, let's start by simplifying: 4( x / 2 - 5 ) + 250 = 1636 2( x - 10 ) + 250 = 1636 2x - 20 + 250 = 1636 2x + 230 = 1636 2x = 1406 x = 703 So, the original number is 703.
