Turning off alarm while asleep

So i have this alarm app on my phone where you have to solve 3 simple math problems for it to turn off. It used to work great for getting me out of bed but my brain figured out how to do it while asleep. I'll set an alarm at 9am for example and I'll end up waking up at 12 with no memory of my alarm going off or solving the math problems. Sometimes I'll set like 2 or 3 which works better but I still think it's fascinating how my brain adapts to solving math problems in my sleep. I'm sharing this only because it's funny and shows how much I hate waking up early.
