write two 2-digit numbers using each of the digits 1, 2, 3, and 4 only once. then find the sum of the numbers. what are the greatest and least possible sums that can be in made in this way?

so far for my greatest, I have 41 and 32 = 73

and 14 and 23 = 37 for my lowest.

Yes. You want the two big digits in the tens place for the big one, and you want them in the units place for the small one. So

41 + 32, or 42 + 31, and

14 + 23 or 13 + 24

are the best you can do.
