Not trying to destroy your pun, but the "s" in "sechs" is actually pronounced like the English "z".
It took me a minute to get it. Thanks Oomph! for teaching me to count in German before I even studied German.
I used to think it was more funny when I didn't know a lot. Now I know for example that ''sechs'' is pronounced like the English ''z'' in zebra or zoo for example. Nice joke though!
Difference means subtraction, so your answer should be -2 (zwei negativen?). Sorry, math geek :)
