there are 5 national parks in louisiana. mississippi has 7 national park. alabama has 5 national parks. think about adding those three numbers. which two numbers would you add first? why?

I don't see that it makes any difference. Which two would you add first?

I would add 5 and 5 first because that equals 10, and its easy to add things to 10

To add the three numbers, we need to add them in pairs. Let's compare the numbers and find the two smallest numbers:

Louisiana: 5 national parks
Mississippi: 7 national parks
Alabama: 5 national parks

The two smallest numbers are 5 and 5 (from Louisiana and Alabama).

Now, we will add these two numbers: 5 + 5 = 10.

Therefore, we would add the numbers for Louisiana and Alabama (5 and 5) first.
