Which of the following is arithmetic operator in javascript?

Arithmetic Operators : +, -, *, /

In JavaScript, arithmetic operators take numerical values [either literals or variables] as their operands and return a single numerical value. There are four standard  arithmetic operators, addition [+], subtraction [-], multiplication [*], and division [/].

These operators work as they do in other programming languages except the division [/] operator which returns a floating-point division in JavaScript, not a truncated division as it does in languages such as C or Java.

  For example:
1/2  returns 0.5 in JavaScript.
1/2  returns 0 in Java.

In addition, JavaScript provides modules[%], increment[++], decrement[--] and unary negation[-] operators.

Example : [ + addition operator]

JS Code:

var var1 = 45;
var var2 = 78;
var var3 = 45.10;
var var4 = 178.12;
var newvar  = var1 + var2;
var newvar1 = var3 + var4;
var newParagraph3 = document.createElement["p"];
var newText3 = document.createTextNode["var1 + var2 = "+newvar+" and var3 + var4 = "+newvar1];
newParagraph3.appendChild[newText3];
document.body.appendChild[newParagraph3];
