<?php

$name= 'crazyfrog';
$action = ' is coming to town.';
$n1 = 8;
$n2=9;

echo $name.$action;
echo '<br>';
echo '8 + 9 = ' . ($n1+$n2);
echo '<br>' . (8*9);

1 doubt

does php use any preference rules from maths?
like BODMAS (Bracket, of, division, multiplication, addition, subtraction) rule or something?
when echoed does the compiler compiles the things in bracket first?

i had an error when i omitted the bracket of 8*9

echo '<br>'.(8*9); 

had error with this code.

echo '<br>'.8*9;

@Austinwhite Please don't ask too much complicated maths questions. No one here understand BODMAS or preference rules from maths

echo '<br>'.8*9; 

I think PHP is confused about that to do here. So it is better use brackets when you use maths operation.
