How do I print a division symbol and parenthesis?

I am trying to use the ASCII characters to add a division symbol and open & closed parenthesis, but this is not printing correctly.


a is a variable, and the calculation is: a / (1 - a)

Do I just have the wrong codes? Should I be looking up decimal or hex?

Thanks

What's wrong with using the characters directly?

I did not realize I could use parenthesis in quotes, but I would like to show the division symbol to show students which key to press on their calculators.

Thanks

assuming you want to print a '\' character, you have to know that it has special meaning inside parens. usually it means "hey, treat the next character as something special" - as in the case of "\n" means "treat the 'n' as a 'newline' character". This is commonly referred to an "escaped n". the backslash is referred to as the escape character.

so how to you print the escape character? you ESCAPE IT!!!

System.out.println("this will print a single backslash: \\)";

if you want a single frontslash, you can just print it:

System.out.println("this will print a single frontslash: /");
