Math question: What is the sum of the digits of the number 1288?

To calculate the sum of the digits in 1288, we break down the number into its constituent digits - 1, 2, 8, and 8. Taking their sum, we have 1 + 2 + 8 + 8 = 19. Therefore, the sum of the digits in the number 1288 is 19.

Math Question: What is the sum of the digits when the number 1288 is multiplied by its reverse?

To find the reverse of 1288, we can write it as 8821 and multiply it by 1288, resulting in 11316248. Now, let's add the individual digits together: 1+1+3+1+6+2+4+8 = 26. Hence, the sum of the digits when 1288 is multiplied by its reverse is 26.

Math question: If I divide a number by 4, multiply it by 2, subtract 10, and then add 100, the result is 1288. What is the original number?

Let's call the original number x. According to the given conditions, we can set up the equation: (((x/4)*2)-10)+100 = 1288. Simplifying the equation, we get (x/2)-10+100 = 1288. Combining like terms, we have (x/2)+90 = 1288. Subtracting 90 from both sides, we get (x/2) = 1198. To isolate x, we multiply both sides by 2, which gives us x = 2396. Therefore, the original number is 2396.
