The formula to calculate the difference between two numbers \(X\) and \(Y\) is:
\[ D(X-Y) = X - Y \]
Where:
The difference between two numbers is the real number obtained after subtracting one number from another.
Let's assume the following values:
Using the formula:
\[ D(X-Y) = 20 - 5 \]
Evaluating:
\[ D(X-Y) = 15 \]
The difference between \(X\) and \(Y\) is 15.
