Math question: What is the sum of all the prime numbers between 1900 and 2000?

To find the sum of all prime numbers between 1900 and 2000, we first identify the prime numbers within this range. Starting from 1900, we progress through each number to check its primality. After identifying the primes, which are 1901, 1907, 1913, 1931, 1933, 1949, 1951, 1973, 1979, 1987, 1993, and 1997, we sum them all. Adding these primes together, 1901 + 1907 + 1913 + 1931 + 1933 + 1949 + 1951 + 1973 + 1979 + 1987 + 1993 + 1997, we get a sum of 23124. Therefore, the sum of all prime numbers between 1900 and 2000 is 23124.

Math question: What is the sum of the digits in the number 1900?

To find the sum of the digits in the number 1900, we first break it down. The digit 1 is in the thousands place, the digit 9 is in the hundreds place, the digit 0 is in the tens place, and the digit 0 is in the ones place. Adding these digits together, 1 + 9 + 0 + 0 gives us a sum of 10. Hence, the sum of the digits in the number 1900 is 10.

Math question: How many different 4-digit numbers can be formed using the digits 1, 9, 0, and 0, with no repetition and both zeroes not appearing consecutively?

To solve this question, we can consider the possible positions for the two zeroes. Since the zeroes cannot appear consecutively, they can either be in the first and third positions or in the second and fourth positions. Case 1: Position 1 and 3 contain the two zeroes: We have 2 choices for the first position (1 or 9), 1 choice for the second position (non-zero), and 1 choice for the fourth position (non-zero). Thus, there are 2 * 1 * 1 = 2 different numbers. Case 2: Position 2 and 4 contain the two zeroes: Again, we have 2 choices for the first position (1 or 9), 1 choice for the third position (non-zero), and 1 choice for the fourth position (non-zero). Therefore, there are 2 * 1 * 1 = 2 different numbers. Combining both cases, we get a total of 2 numbers + 2 numbers = 4 different 4-digit numbers that can be formed using the digits 1, 9, 0, and 0, with no repetition and both zeroes not appearing consecutively.
