PHP Math functions for addition, subtraction, multipication & divisionSimple PHP functions to handle addition , subtraction , multiplications and divisions can be done by using built in functions.
Best way to learn is to develop some sample scripts.
Here are some of them.
Let us start with simple addition of two variables storing numbers.
$a=5;
$b=6;
$c=$a+$b;
echo $c;
Now try a subtraction.
$a=8;
$b=10;
$c=$a-$b;
echo $c;
Multiplication
$a=3;
$b=14;
$c=$a*$b;
echo $c;
Division
$a=3;
$b=14;
$c=$a/$b;
echo $c;
The output of division can be formatted to required decimal places
