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.
can anyone tell me if i got it right?
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.
Yes, you are correct! You have found two sets of 2-digit numbers using each of the digits 1, 2, 3, and 4 only once.
For the greatest sum, you correctly chose the numbers 41 and 32. Adding 41 and 32 together gives you 73.
For the lowest sum, you correctly chose the numbers 14 and 23. Adding 14 and 23 together gives you 37.
Well done on finding the correct answers!
