I need a good thinking trivia question for my Math club

[matt000]

I'm doing this for extra credit for my teacher and I have NO IDEA where to get any problems.
In the past, my friends did... something like a = b (long lines of equation) and we had to find what's wrong. It took a while, but the club got it.
I want something like that. It can be at around prerecalculus level. I don't know what to think of ...

Please help me...

THANK YOU!

EDIT:: (I'll need an answer with it also if possible, or the work, thank you so much)

Here is a fun one:
What does this code generate?

c = y / 100
n = y - 19 * ( y / 19 )
k = ( c - 17 ) / 25
i = c - c / 4 - ( c - k ) / 3 + 19 * n + 15
i = i - 30 * ( i / 30 )
i = i - ( i / 28 ) * ( 1 - ( i / 28 ) * ( 29 / ( i + 1 ) )
* ( ( 21 - n ) / 11 ) )
j = y + y / 4 + i + 2 - c + c / 4
j = j - 7 * ( j / 7 )
l = i - j
m = 3 + ( l + 40 ) / 44
d = l + 28 - 31 * ( m / 4 )

is the answer zero ?

crude, i forgot to say I'll need an answer also ! sorry for the trouble again. Thank you for the question thought, I'll probably use it.

:rofl: You want the answer! No, it is not zero.

I was able to figure out this when it was presented to me. What got me on the right track was realizing that y must stand for year. Try starting with a year, go through the calculations...

It calculates the date of Easter.
