Answer 2

Let's evaluate the given expressions step by step:

1. 5 + 8 = 13
2. (+) = 13 (since the first expression is 5 + 8)
3. (+)+= 13+= (We replace the second set of asterisks with the result of the first expression, which is 13) = 13 + 13 = 26
4. **+*= (We replace the first set of asterisks with the result of the first expression, which is 13) = 13 + 26 = 39

So, the values of the given expressions are:

1. 5 + 8 = 13
2. (+) = 13
3. (+)+*= 26
4. **+*= 39
