Math Question: How many distinct four-digit numbers can be formed using the digits 2, 4, 5, and 6 without repetition?

To find the number of distinct four-digit numbers, we need to consider the possible choices for each digit in the thousands, hundreds, tens, and units place. For the thousands place, there are 4 choices (2, 4, 5, 6). After selecting the thousands digit, we are left with 3 choices for the hundreds place. Similarly, we have 2 choices for the tens place and only 1 choice for the units place. Using the multiplication principle, the total number of distinct four-digit numbers is obtained by multiplying the number of choices for each place: 4 × 3 × 2 × 1 = 24. Hence, there are 24 distinct four-digit numbers that can be formed using the digits 2, 4, 5, and 6 without repetition.

What is the sum of the digits in the number 2456?

To find the sum of the digits, we add the individual digits together. The sum is 2 + 4 + 5 + 6 = 17.

Math Question: What is the sum of the digits in the number 2456?
