How do you write "3 more than the sum of x and y"

3+(x+y)

To write "3 more than the sum of x and y," you can use the following expression:

(x + y) + 3

Here's how you can break it down and understand the logic:

1. Start with the sum of x and y, which is represented by (x + y).
2. Since you want to add 3 more to this sum, you simply add 3 at the end.

So, the expression (x + y) + 3 represents 3 more than the sum of x and y.
