Overview
In this tutorial, we will learn about MySQL Arithmetic operators with examples.
MySQL Arithmetic Operators
Arithmetic operators are used to perform mathematical operations like addition, subtraction, etc on the column values. MySQL arithmetic operators are as follows:
| MySQL Arithmetic Operator | Description |
| + | Addition |
| – | Subtraction |
| * | Multiplication |
| / | Division |
| DIV | Integer Division |
| % | Modulo – Remainder after integer division |
Operator Precedence
The arithmetic operators have the following precedence.
* multiplication, / Division, % Modulo
– Subtraction, + Addition
Multiplication , Division, Modulo have higher precedence over the Subtraction and Addition operators.
Examples
mysql> SELECT 7 + 9;
+——-+
| 7 + 9 |
+——-+
| 16 |
+——-+
1 row in set (0.02 sec)
Modulus operator
mysql> SELECT 17 % 3;
+——–+
| 17 % 3 |
+——–+
| 2 |
+——–+
1 row in set (0.00 sec)
Returns the remainder after the integer division.
#
mysql> SELECT 2 * 3 + 7;
+———–+
| 2 * 3 + 7 |
+———–+
| 13 |
+———–+
1 row in set (0.00 sec)
mysql> — The * operator has high precedence over +
mysql> — 2 * 3 + 7 -> 6 + 7 -> 13
mysql> — result = 13
mysql> — If + had higher precedence then the result would
mysql> — have been 20! But, It’s NOT the case
