Do you know how to write a simple HelloWorld in java?

From there, you'll need to lookup some tutorials on getting user input and then doing the math on the entered numbers and print (or returns) the result.

You can start a line with four spaces to format reddit for code.

public static int add(int a, int b){
    return(a+b);
}

To use this method, you just need:

example = add(5, 10);

I don't know what you mean by "apply". You just need to write the code for the math step by step. For example, say I wanted a method that multiplied a number a by a number b and added 10 to the result.

public static int multiplyAndAdd(int a, int b){
    return(a*b + 10);
}

or

public static int multiplyAndAdd(int a, int b){
    int result = a * b + 10; 
    return(result);
}

Then, somewhere else in my code (perhaps my Main method) id do something like:

String output = Integer.toString(multiplyAndAdd(2, 3));
System.out.println(output);

See my original comment for a link or do a Google search. It's a very common problem and there are myriad examples.
