Simple Javascript maths

Question

I'm trying to work with some maths, and I can't get a negative number to act as a positive number. I have these numbers in different variables;

330 3106 -2776

I need 330, 3106 and 2776 so I can do this statement (obviously they will be vars though!);

if((2776 + 330) == 3106){ 

}

Is there a shorthand or quick method I can use to do this inside of my if statement? Id rather not have to make more variables to do this...

Thanks

if((Math.abs(-2776) + 330) == 3106){ 
  //...
}

You can use Math.abs() on a number to ensure it's positive.

Math.abs(-123);  // 123

Math.abs(123);   // 123

You could use Math.abs() method.

Math.abs(-2276) === 2276
