Hey everyone,

I'm currently learning PHP and I'm a bit confused about how to perform basic arithmetic operations in it. I understand the concept of arithmetic operations like addition, subtraction, multiplication, and division, but I'm not sure how to actually implement them in my PHP code.

For example, let's say I want to add two numbers together. How would I do that in PHP? And what about subtracting, multiplying, and dividing numbers? Are there any specific functions or syntax I need to use?

I would really appreciate it if someone could walk me through the basics of performing arithmetic operations in PHP. Maybe you could even provide some code examples to help me understand better.

Thank you in advance for your help!

Hi there!

I remember when I started learning PHP, I found arithmetic operations to be quite simple to implement. In PHP, you can perform basic arithmetic operations using the arithmetic operators like `+`, `-`, `*`, and `/`.

To illustrate further, let's take the example of multiplying two numbers:

In this code, we define two variables `$num1` and `$num2` with the values 8 and 2 respectively. Then, we use the asterisk (*) operator to multiply them together and store the result in the variable `$product`. Finally, we use the `echo` statement to display the product on the screen.

Similarly, you can use the plus (+) operator for addition, the minus (-) operator for subtraction, and the slash (/) operator for division. Just make sure to adjust the variables and operator accordingly.

Remember, you can also combine numbers and variables in arithmetic operations. For example:

In this case, we're multiplying `$num2` by 2 and then adding it to `$num1`. The result will be displayed using the `echo` statement.

I hope this clears things up for you. Feel free to ask if you have any more questions or need further clarification!
