How do I perform addition, subtraction, multiplication, and division operations in PHP?

Hey folks!

I've been working with PHP for quite some time, so I'd love to share my experience on performing basic mathematical operations in PHP. PHP offers various operators to carry out addition, subtraction, multiplication, and division.

To perform an addition in PHP, you can use the "+" operator. Here's an example:

php
$number1 = 7;

$number2 = 3;

$result = $number1 + $number2;

echo $result; // Output: 10

php
$number1 = 12;

$number2 = 5;

$result = $number1 - $number2;

echo $result; // Output: 7

php
$number1 = 4;

$number2 = 9;

$result = $number1 * $number2;

echo $result; // Output: 36

php
$number1 = 20;

$number2 = 4;

$result = $number1 / $number2;

echo $result; // Output: 5

Hey there,

Performing basic mathematical operations in PHP is actually quite straightforward. You'll be happy to know that PHP has built-in operators for addition, subtraction, multiplication, and division.

To start with addition, you can simply use the "+" operator. Here's an example:

php
$a = 5;

$b = 3;

$result = $a + $b;

echo $result; // Output: 8

php
$a = 10;

$b = 4;

$result = $a - $b;

echo $result; // Output: 6

php
$a = 6;

$b = 7;

$result = $a * $b;

echo $result; // Output: 42

php
$a = 20;

$b = 5;

$result = $a / $b;

echo $result; // Output: 4

To perform addition, you can use the "+" operator. Here's an example:

php
$num1 = 8;

$num2 = 4;

$result = $num1 + $num2;

echo $result; // Output: 12

php
$num1 = 15;

$num2 = 7;

$result = $num1 - $num2;

echo $result; // Output: 8

php
$num1 = 5;

$num2 = 6;

$result = $num1 * $num2;

echo $result; // Output: 30

php
$num1 = 20;

$num2 = 4;

$result = $num1 / $num2;

echo $result; // Output: 5
