PHP programming is based on operators and operands. If you are already learned operators in C language, you will understand easily. You can use mathematics formula (a+b) in PHP language. First of all, you need to learn about PHP data types.

Think about the variables in mathematics formula (a+b)2 There is two variable in this formula a and b.

How to open the mathematics formula (a+b)2  


How can write the line mathematics line a2+b2+2ab


if a=2 and b=4



= 4+16+16


You can use this mathematics logic in PHP programming


Asterisk sign (*) is used for multiplication in computer programming languages.

We declare the variables in PHP like this –
