³ Common Mistakes ³

ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ

WRONG f(a + b) = f(a) + f(b) RIGHT No formula for f(a + b)

WRONG f(a + b) = f(a) + b RIGHT No formula for f(a + b)

WRONG Solving x f(x) = O and forgetting that x = O is a solution.

WRONG Solving f(x)/x = O and thinking that x = O is a solution.

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
