144....
And here's the formula...
$result = $a * ($a + $b);
if we want to make it a loop out put...using php for example...
PHP Code:
<?php
$a = 10;
while ($a != 0):
$b=0;
while ($b != 10):
$result = $a * ($a + $b);
echo ( $a . ' + ' . $b . ' = ' . $result . "<br />");
$b++;
endwhile;
$a--;
endwhile;
?>
Then the list of results you can pick from?
