Question: How many different 3-digit numbers can be formed using the digits 2, 4, 9, and 3, without repetition, considering each digit must be used exactly once?

To find the number of different 3-digit numbers, we start by choosing the digit for the hundreds place, which can be any of the 4 given digits. After selecting one, we have 3 remaining digits for the tens place, and once that digit is chosen, we are left with only 2 digits for the units place. Thus, the number of different 3-digit numbers is 4 × 3 × 2 = 24.

Question: What is the sum of the digits in the number 2943?

To find the sum of the digits in the number 2943, we add each digit separately. The digit 2 + 9 + 4 + 3 equals 18.

Math Question: What is the smallest prime number greater than 2943 which is divisible by 5?

The smallest prime number greater than 2943 that is divisible by 5 can be found by checking numbers one by one. Starting from 2944, we find that 2953 is divisible by 5 and also a prime number. To check its primality, we look for divisors up to the square root of 2953, which is approximately 54.26. Dividing 2953 by all numbers up to 54, we find no divisors other than 1 and itself, indicating its primality. Therefore, the answer is 2953.
