using four different digits, what is the least sum you can get when you add two 2-digit numbers? Write your problem
13 + 24
Why is top answer 13 +24
0+1
To find the least possible sum when adding two 2-digit numbers using four different digits, follow these steps:
1. Begin by selecting the smallest digit, which is 1.
2. Assign 1 to the tens place of one of the 2-digit numbers.
3. For the second 2-digit number, assign 0 to the tens place since the number must be different.
4. Next, choose the next smallest digit, which is 2.
5. Assign 2 to the ones place of the first 2-digit number.
6. Assign 3 to the ones place of the second 2-digit number.
7. Now, arrange the digits in the tens and ones place to form two 2-digit numbers.
8. The smallest possible sum can be obtained by adding the two 2-digit numbers together.
So, the problem can be written as finding the least sum when adding 10 and 23.
