Math alarm clocks: do they actually work?

What arithmetic-based alarms are good at, who they fail for, and how to set the difficulty so you keep using it past week two.

The short answer

Math alarms work well for one specific failure mode: dismissing an alarm while half asleep and not remembering it. They work considerably less well for people who solve the problem in bed and then drift back off, which is a different problem entirely.

Set one alarm you actually have to earn.

Pick a mission tonight. Tomorrow morning it will not let you dismiss it half asleep — and it will still let you out if you genuinely need to be somewhere.
