🎃 Halloween Collection

The first three of the Halloween collection — built for this Halloween week. The rest of the collection stays in Calc's lab for next season.

How Dummy Math works

Three steps between you and a number you'll immediately want to send to the group chat.

STEP 1
Pick a stupid question. There are no wrong answers, only embarrassing ones.
STEP 2
Answer honestly. Calc runs the real formula — salary math, damages, forensic suspicion scores, all of it.
STEP 3
Get your verdict, share the damage, and download your official certificate. Frame it. Or use it as evidence.

Dumb questions, honest answers

Is the math actually real?

Yes. The questions are ridiculous; the arithmetic is not. Every calculator uses a real formula — your actual hourly rate, actual cleanup hours, actual lifetime bills — shown in the results so you can argue with it.

Do I need an account or payment?

No. No login, no card, no email. Your numbers never leave your browser — the calculators run entirely on your device.

Who is Calc?

Calc the Dummy is our Chief Numbers Officer: a calculator in a purple-and-yellow hat who believes bad decisions deserve data. He has never once been wrong, because math.
