Math question: How many different number combinations can be made using the digits 2, 6, and 8 without repetition?

To find the number of combinations, we can use the concept of permutations. Since we have three digits, there are three positions to fill. For the first position, we can choose any of the three digits (3 choices). Once the first digit is chosen, there are two remaining digits for the second position, and only one digit left for the third position (2 choices and then 1 choice). To find the total number of combinations, we multiply these choices together: 3 × 2 × 1 = 6. Hence, there are 6 different number combinations that can be made using the digits 2, 6, and 8 without repetition.

Math Question: What is the sum of the digits of the number obtained by multiplying 2628 by 3?

To find the sum of the digits, multiply 2628 by 3, which equals 7884. The sum of the digits in 7884 is 7 + 8 + 8 + 4 = 27.

Math question: If 2628 is multiplied by 13 and divided by 9, what is the result?

To find the result, we multiply 2628 and 13, getting 34164. Then, we divide this by 9 which gives us 3796. This means that when 2628 is multiplied by 13 and divided by 9, the result is 3796.
