For preserving the least toxic and most culturally relevant Tumblr heritage posts.

Image descriptions and plain text captions of written content are expected of all screenshots. Here are some image text extractors (I looked these up quick and will gladly take FOSS recommendations):

-web

-iOS

Hmm, you seem to be completely discounting calculus, where a given problem may have 0, 1, 2, or infinite solutions. Or math involving quantum states.

In math, an answer is either right, wrong, or partially right (but incomplete).

Those are quite far from mental arithmetic though

Calculus is generally pretty easy to do mental arithmetic on, especially when talking about real-world situations, like estimating the acceleration of a car or something. Those could have multiple answers, but one won't apply (i.e. cars are assumed to be going forward, so negative speed/acceleration doesn't make much sense, unless braking).

Math w/ quantum states is a bit less applicable, but doing some statics in your head for determining how many samples you need for a given confidence in a quantum calculation (essentially just some stats and an integral) could fit as mental math if it's your job to estimate costs. Quantum capacity is expensive, after all...

Quantum states is physics, not math.

And mathematically a probabilistic theorem is still a theorem.

Yes, but physics is math with more variables.

But there's plenty of math related to quantum states that can make sense, such as if you know a given machine will give the right answer 51% of the time, and you want to know how many iterations you'll need to get a certain confidence that you are seeing the correct answer. That's basic statistics, which is also math, but it's relevant to quantum states in that you're evaluating a computing system based on qubits.
