Question: If a number is multiplied by 7, then added to 4, and the result is 9906, what is the original number?

Let's assume the original number is x. According to the given conditions, 7x + 4 = 9906. To isolate x, we subtract 4 from both sides, which gives us 7x = 9902. Finally, dividing both sides by 7, we find x = 1414. Therefore, the original number is 1414.

Math question: What is the sum of the digits in the number 1418?

To find the sum of the digits in 1418, we break it down as follows: 1 + 4 + 1 + 8 = 14. Therefore, the sum of the digits is 14.
