Math question: What is the sum of the digits in the number 7963?

To find the sum of the digits in the number 7963, we add the individual digits together. 7 + 9 + 6 + 3 = 25 Therefore, the sum of the digits in the number 7963 is 25.

Math question: If you divide a number by 7, multiply by 9, subtract 5, and then add half of the original number, you get 7963. What is the original number?

Let's denote the original number as x. According to the given conditions, the equation can be written as [(x/7) * 9] - 5 + (x/2) = 7963. Simplifying, we have (9x/7) + (x/2) = 7968. Combining like terms, we get [(18x + 7x)/14] = 7968, or (25x/14) = 7968. Multiplying by 14 and dividing by 25, the solution is x ≈ 4495.2. Therefore, the original number is approximately 4495.2.

What is the product of the prime factors of 7963?

To find the prime factors of 7963, we divide it successively by prime numbers starting from 2. After a few divisions, we find that 79 is a prime factor of 7963. Thus, the product of the prime factors of 7963 is 79.
