Math question: What is the sum of the digits in the number 7242?

To find the sum of the digits in the number 7242, we add each digit together. 7 + 2 + 4 + 2 = 15 Hence, the sum of the digits in the number 7242 is 15.

What is the sum of the digits of the number 7242 subtracted from the product of its digits multiplied by the difference between the second and third digits?

To find the sum of the digits, we have 7 + 2 + 4 + 2 = 15. The product of the digits is 7 × 2 × 4 × 2 = 112. The difference between the second and third digits is 2 - 4 = -2. Therefore, the answer is 112 × -2 - 15 = -239.

Math question: What is the sum of the digits in the number 7242?

To find the sum of the digits in the number 7242, we add each digit together. Taking 7242 as the number, we have: 7 + 2 + 4 + 2 = 15. Therefore, the sum of the digits in 7242 is 15.
