Q:

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

Hey everyone,

I'm fairly new to PHP and I'm trying to figure out how to perform basic mathematical operations like addition, subtraction, multiplication, and division in PHP. I've searched online, but I'm still a bit confused about the syntax and how to implement these operations in my code.

I would greatly appreciate it if someone could provide me with some guidance or examples on how to perform these mathematical operations in PHP. Any explanations or sample code would be extremely helpful.

Thank you in advance for your assistance!

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


For subtraction, you can use the "-" operator. Take a look at this example:

php
$number1 = 12;
$number2 = 5;
$result = $number1 - $number2;
echo $result; // Output: 7


Multiplication is simple; use the "*" operator. Check out this example:

php
$number1 = 4;
$number2 = 9;
$result = $number1 * $number2;
echo $result; // Output: 36


Lastly, to perform a division, use the "/" operator. Here's an example:

php
$number1 = 20;
$number2 = 4;
$result = $number1 / $number2;
echo $result; // Output: 5


Feel free to substitute the variables `$number1` and `$number2` with your desired numbers.

If you have any further questions related to PHP or anything else, don't hesitate to ask. Happy coding!

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


For subtraction, use the "-" operator. Here's an example:

php
$a = 10;
$b = 4;
$result = $a - $b;
echo $result; // Output: 6


Next, for multiplication, use the "*" operator. Here's an example:

php
$a = 6;
$b = 7;
$result = $a * $b;
echo $result; // Output: 42


Lastly, for division, use the "/" operator. Here's an example:

php
$a = 20;
$b = 5;
$result = $a / $b;
echo $result; // Output: 4


Remember, these are just basic examples to give you an idea. You can replace the variables `$a` and `$b` with whatever values you need.

I hope this explanation helps you out. Let me know if there's anything else I can assist you with!

Hey everyone,

Performing mathematical operations in PHP is something I've been doing for a while, so I'd be happy to help out. When it comes to addition, subtraction, multiplication, and division, PHP provides easy-to-use operators.

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

php
$num1 = 8;
$num2 = 4;
$result = $num1 + $num2;
echo $result; // Output: 12


For subtraction, you can use the "-" operator. Here's a quick example:

php
$num1 = 15;
$num2 = 7;
$result = $num1 - $num2;
echo $result; // Output: 8


Multiplication is as simple as using the "*" operator. Here's an example:

php
$num1 = 5;
$num2 = 6;
$result = $num1 * $num2;
echo $result; // Output: 30


Lastly, for division, use the "/" operator. Here's an example:

php
$num1 = 20;
$num2 = 4;
$result = $num1 / $num2;
echo $result; // Output: 5


These examples should demonstrate how to perform basic mathematical operations in PHP. Feel free to replace the variables `$num1` and `$num2` with your own values.
