Oh, isn't that a happy little question. Let's say we have the mixed numbers 2 1/2 and 1 1/2. When we add them together, we get a sum of 4, which is a lovely whole number. Just like that, we've created a beautiful harmony on our canvas of numbers.
11/3 and 12/3
2 and 1
1 1/2 + 1 1/2 = 3
2 1/2
10 + (-3) = 7 10 - (-3) = 13 10 and -3
1 1/4 and 1 3/4
10
The answer to your question is 10 and three.10 + 3 = 13 (Sum)10 - 3 = 7 (Difference)I hope this helps.
11/3 + 12/3 = 3 (is one example only)
1 1/2 + 1 1/2
1 1/2 + 1 1/2
