Arithmetic Subtraction

- symbol is used for arithmetic subtraction operator.

arithmetic subtraction operator takes two values/variables as operands and returns the difference of right side operand from the first operand.

a - b  //variables
6 - 4  //values

more than one value/variable can be subtracted from a value in a single expression by chaining subtraction operator.

a - b - c - d        //variables
6 - 4 - 5 - 10 - 85  //values

Examples

1. subtraction of b from a

var a = 10;
var b = 25;

var diff = a - b;

console.log(diff);

2. subtraction of more than one value/variable from a value

var a = 10;
var b = 25;
var c = 14;

var diff = a - b - c;

console.log(diff);
