HAHAHAHA YOU STUPID DUMBFUCK

>Hmm... 426 + 793. Let me analyze these two numbers...
>Ah! 426 is one more than 425. Now what do I do with it?
>It's obvious! I'll take that 1 I removed off of 426 and add it on to 793
>Now I have 425 + 794. Now I'm getting somewhere! Well I know 425 is a multiple of 25... But what can I do with that?
>Hmmm... Perhaps nothing.
>Should I have even removed the 1 from 426? Let me get back to my original form
>426 + 793. There we go. That's better. But it seems I've gotten nowhere.
>Perhaps I can draw some squares.
>Draws squares
>There we go! 426 squares and 793 other squares. Let me count them
