ITS IMPOSSIBLE

In the main method, place plus and minus signs correctly so that the variable result is equal to 20.
Signs must be placed only in the line where the variable result is declared.
Do not change the order of the variables in this line.
Each variable must be preceded by either a plus or minus sign.

Requirements:

Values of variables: Do not change a, b, c, or d.
Each of the variables (a, b, c, and d) in the line where the variable result is declared must be preceded by either a plus or minus sign.
The program should display the number 20 on the screen.
The plus and minus signs must be placed correctly.

package com.codegym.task.task01.task0137; /* Only 20 will do */ public class Solution { public static int a = 1; public static int b = 3; public static int c = 9; public static int d = 27; public static void main(String[] args) { int result = +a + -b + c + d; System.out.println(result); } }

It is simple. Only use symbol(either + or -) in front of the variable name. For example: Assume a=5, and b=6. If you write +a +b , it means +5+6 , which is equal to 11. If you write -a+b, it means -5+6, which is equal to 1. Remember:You only have to add one symbol!

There is no such a thing like this: +a + -b. Either a + b or a - b you can't use 2 arithmetical operator in one spot.

You just have to remember that int = integers. They can be positive or negative from the start
