Question: If the number 1818 is multiplied by 4 and then 50 is added to it, what is the resulting value?

To find the answer, we multiply 1818 by 4, which gives us 7272. Adding 50 to this value, we get a final result of 7322. Therefore, if the number 1818 is multiplied by 4 and then 50 is added to it, the resulting value is 7322.

Math question: What is the remainder when 1818 is divided by 7 and then multiplied by the sum of its digits?

To find the remainder when 1818 is divided by 7, we get 259 as the quotient with a remainder of 5. The sum of the digits of 1818 is 1+8+1+8=18. Multiplying the sum by the remainder, we get 18*5=90. Therefore, the answer is 90.

Math question: What is the smallest prime number greater than 1818?

The smallest prime number greater than 1818 is 1823. A prime number is one that is only divisible by 1 and itself, and by checking numbers greater than 1818, we find that 1823 is not divisible by any other number apart from 1 and itself, making it the next prime number after 1818. Prime numbers have a significant role in various mathematical applications, such as cryptography, number theory, and prime factorization.
