What does that mean?

What does that mean?

got that one on the first try AWESOME!!!

AHHHHHHHH I can't believe I fell for that one. Great teaser.

If we can live in a world where 2=6, then why should we assume that the transitive properties of an equal sign hold?

I can not believe I fell for it!! I thought 5=9. Great teser

Modulo 4 arithmetic means that you always divide the answer by 4 and only care about the remainder.

So 3 (mod 4) + 3 (mod 4) = 6 (mod 4), which equals 2 (mod 4).

Often used in data coding. Also quite common in programming.

I was tricked. Simple but slippery. Good one

Why is this in logic? It should be in trick...

Are there really prople out there that thought this was hard, who actually didn't get it?

I'm not quite sure why this was suppose to be hard...I mean it's like saying 1=5 what does 5= ... I mean if there were no variables, the other numbers are irrelivent.... But if people liked it and had fun, then more power to ya.

HAHA that was really cute

good job

good job

i really liked that, you totally tricked me

I thought it was 5(since it was logic)

i also thought it was nine.

Haha, I got that one right.

Tricky, but easy if you read it carefully. I do, however, agree with Punk Rocker that it belongs in the trick category.
