What is the sum of all the prime numbers less than 1794?

To find the sum of prime numbers less than 1794, we begin by listing all possible primes: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47... Eventually, we find that the last prime number less than 1794 is 1789. Now, we sum all these primes: 2+3+5+7+11+13+17+19+23+29+31+37+41+43+47+...+1789. To calculate this sum, we can employ the formula for the sum of an arithmetic series, Sn = n/2 * (a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. Using this formula, we have Sn = (n/2) * (a + l) = (166/2) * (2 + 1789) = 83 * 1791 = 148,833. Thus, the sum of all prime numbers less than 1794 is 148,833.

Math question: If you subtract the sum of the digits in the number 1794 from the product of its digits, what is the result?

To find the product of the digits in 1794, multiply 1, 7, 9, and 4 together: 1 x 7 x 9 x 4 = 252. The sum of the digits is 1 + 7 + 9 + 4 = 21. Subtracting the sum from the product: 252 - 21 = 231. Hence, the result is 231.

Math question: If a number adds up to 1794 and half of it is subtracted from the original number, what is the result?

Let's assume the original number is x. We are given that x + (x/2) = 1794. Multiplying both sides by 2 gives 2x + x = 2 * 1794, simplifying to 3x = 3588. Dividing by 3, we find x = 1196. Therefore, subtracting half of 1196 from 1196 yields the result of 598.
