I got bored in my class the other day so I started messing around with squares and how to make them without multiplying. Heres a php script demonstrating what I found:

<?php

$previousnumber = 0;

for($i = 0; $i < 100; $i++){

$number = $previousnumber + $i + $i + 1;

$previousnumber = $number;

echo ("$number");

echo ("<br>");

}

?>

basically

0 + 0 + 0 + 1 = 1

1 + 1 + 1 +1 = 4

4 + 2 +2 +1 = 9

answerbefore + current number to be squared + current number to be squared+ 1 = number squared

p+2x+1=y(formula I made to show it)

Point of this thread?

Show something intresting many people will never notice.
