Most of you probably won't have troubles with this but i didn't get it at first.
Without the use of a calculator, what is 111111111*111111111. The answer is kind of cool so you'll know if you get it or not.

Hint: Once you've done the text you want to space, enclose it in code tags.
Oh ya, leading blanks are lost even in code, so put some non-blank character first:

.		111111111
.	   111111111
.	  111111111
.	 111111111
.	111111111
.   111111111
.  111111111
. 111111111
.111111111

Spoiler for 111111111^2


My uncle also once gave me something cool about math:

1*8+1= 9
12*8+2= 98
123*8+3= 987
1234*8+4= 9876
12345*8+5= 98765
an so on...
123456789*8+9=987654321

12345678987654321

have you tried this?

12345679*9=111,111,111

12345679*18=222,222,222

12345679*27=333,333,333

...

12345679*81=999,999,999

no edit. its 12345679, not 123456789
