Add Operator
Category:Math
All programming languages support the basic arithmetic operations of addition, subtraction, multiplication and division of numbers. The addition operator is also used to add, or concatentate, two strings together.
Examples
Adding a Few Things
Combining different values with addition
// Add numbers, add strings,
// and add variables
// containing numbers.
write(3+5);
write("3"+"5");
var x=3;
var y=5;
write(x+y);
Syntax
value1 + value2;
Parameters
| Name | Type | Required? | Description |
|---|---|---|---|
| value1 | Any | First value to be added or concatenated | |
| value2 | Any | Second value to be added or concatenated |
Returns
The sum of two numbers or concatenation of two strings
Tips
- Operator precedence is the same as standard arithmetic - Expressions within a parentheses have the highest precedence, then multiplcation and division, then addition and subtraction.
- If either one of the operands are a string it treats the addition as string concatentation.
