What is the sum of the digits in the number 2913?

To find the sum of the digits, we add them individually: 2 + 9 + 1 + 3 = 15. Therefore, the sum of the digits in the number 2913 is 15.

Math Question: If the number 2913 is multiplied by 5, divided by 3, and then subtracted by 800, what is the result?

To find the result, we'll start by multiplying 2913 by 5, which gives us 14,565. Next, we divide this by 3, resulting in approximately 4,855. Finally, subtracting 800 from this gives us the final answer of approximately 4,055. Thus, when considering the operations mentioned and the number 2913, the result is approximately 4,055.

Math Question: How many unique three-digit numbers can be formed using the digits 2, 9, 1, and 3 if repetition is not allowed?

To determine the number of unique three-digit numbers, we can use the concept of permutations without repetition. Since we have 4 digits available, and we can choose 3 digits at a time without repetition, we can calculate it as 4P3 (denoting the permutation of 4 items taken 3 at a time). Using the formula for permutations: P(n,r) = n! / (n-r)!, where n represents the number of items and r represents the number of items taken at a time, we can compute: 4P3 = 4! / (4-3)! = 4! / 1! = 4 Therefore, there are 4 unique three-digit numbers that can be formed using the digits 2, 9, 1, and 3. These numbers are: 291, 213, 913, and 132.
