Make the largest and smallest numbers you can find using the digits: 4,1,7,8,5 and 2. Find their difference and sum.
1. I do not know if I have to use all the digits.
2. If I do not need to use all of the digits won't there be a lot of the numbers.
3.I do not get the part that says find their diffrernce and sum.
Please help me. Thank you.

I assume you must use all of the digits.
The smallest starts with 1. The largest starts with 8.
After you've found the two numbers, add them to find their sum. Then subtract the smaller number from the larger number to find the difference.
