The formula to calculate the sum of two numbers \(X\) and \(Y\) is:
\[ S(X+Y) = X + Y \]
Where:
The sum of two numbers is the total value obtained after adding two real numbers.
Let's assume the following values:
Using the formula:
\[ S(X+Y) = 20 + 5 \]
Evaluating:
\[ S(X+Y) = 25 \]
The sum of \(X\) and \(Y\) is 25.
