Uniform Stealing Board

Does anyone know how to actually register to join the chloro forum.
At the end of the form to register, they have a question to answer that's just a bunch of numbers. I tried adding them, subtracting them, everything and no go. Does anybody know what it means?
Please help, if possible.
Thank you.

Do you mean the security question that is 2+2-3x4? The answer is 4.

Oh! What a dumbass! I didn't get that. Thanks, Blue-Cynthia. You're a big help.

Is this the same Chloroforum from about 20 years ago with a reboot or a totally diff page?
