Any mental mathletes here?

I can rapidly mentally divide extremely long numbers by some digit (like 3), up to many decimal points.
Also, I can mentally extract square roots of perfect squares that are up to 4 digit long. I think I did some square root extractions of 6 digit long numbers, but that was rather difficult.
This one isn't really fast mental math, but I can also rapidly memorize a very big amount of digits in a short period of time. My record was memorizing 100 digits in just 15 minutes. (I can memorize up to as many digits as I want provided that I have enough time - I haven't found a limit for that yet.)
Also, wanted to add that I don't exactly have a mild Autism Spectrum Disorder. In my case, it affects language and communication to some extent, and the last tests I had showed very huge discrepancies between different cognitive abilities - some were literally absent, some were very developed. For example, ironically, I was unable to solve any (not even one!) arithmetic problems that were presented verbally during the testing, despite boasting a rather good GPA in math and very good mental math skills - the verbal information during the test simply overwhelmed my sensory system.

I've boasted a lot in this thread already, but only because I'm proud of it.
I can square root numbers that aren't perfect squares too

Do you use the mental abacus method too? I tried square rooting long imperfect squares, but it's very complicated, and I end up making mistakes half the time (so I stay with moderately long perfect squares).

I think I really need to practice and work on the long imperfect square extraction. I tried it only a few times (about 2-3 times) and decided to abandon it, but I will try it again and see if practice will help.
I used to make mistakes at first when making mental calculations I excell at now too. I think I gave up on mentally calculating long imperfect squares (ex: square root of 486347.857) too early.

Do you consciouslly do these calculations? When did you first start doing them? How long does it take for you to calculate very long imperfect squares?
The way I do it is via the mental abacus method with some modifications.

Well, I don't exactly use this method, but it gave me an insight into how to make long square root extractions possible given my cognitive profile.

I just seem to do them. Someone says 1259*3828 and I instantly say 4819452.
It takes no time at all for me to calculate anything really, no matter what calculation it is.
As for how long: before I could even talk. I started showing them after I could talk as well as my memory skills. However I just assumed everyone could do it and kept it to myself a lot. It was only when my year 1 teacher told my parents about it and explained that she had never seen anything so extraordinary that I realised. After that I showcased it more and received attention a lot. My parents still fondly remember me at a young age going into a Church, glancing at the notice board and remembering it all. I can still recite it all too like everything else.

This really does seem very impressive. Can you do very long divisions? What ASD are you diagnosed with? Do you do fast calendar calculations? What other calculations do you do? Do you have some other impressive abilities too?

Yes I can do very long divisions at the same speed as everything else. I'm diagnosed with autism. I can do calendar calculations and anything else involving calculations.
Other special abilities...I've said them in the general discussion thread under the abilities thread.
Would I qualify as a savant, a prodigious one perhaps?

As for how long: before I could even talk. I started showing them after I could talk as well as my memory skills. However I just assumed everyone could do it and kept it to myself a lot. It was only when my year 1 teacher told my parents about it and explained that she had never seen anything so extraordinary that I realised. After that I showcased it more and received attention a lot. My parents still fondly remember me at a young age going into a Church, glancing at the notice board and remembering it all. I can still recite it all too like everything else.
This really does seem very impressive. Can you do very long divisions? What ASD are you diagnosed with? Do you do fast calendar calculations? What other calculations do you do? Do you have some other impressive abilities too?
Yes I can do very long divisions at the same speed as everything else. I'm diagnosed with autism. I can do calendar calculations and anything else involving calculations.
Other special abilities...I've said them in the general discussion thread under the abilities thread.
Would I qualify as a savant, a prodigious one perhaps?
Yes, this is a strong possibility. You seem to have a rather exceptional performance in many fields which savants are good at. You should probably start making YouTube videos demonstrating your skills - you could make money and friends from this. You should use your talents and show them to the world. If you ever make a YouTube video, send me a PM with a link. Also, if you do get some popularity, you could set up a website. I work as a web designer and sysadmin as a side job, so I could help you free of charge if you want.
I can only do the long divisions very fast and up to any number of decimal points, as well as fast memorization. I'm worse at other calculation skills. But, I'm pretty good at academic fields (math, economics, computer science), as well as programming.

I aim to do a YouTube channel in the distant future, and will probably still be a member by then so will PM you the link. I was doing my usual performance to people today, it makes me feel very popular. I am very popular in fact.
Why the distant future? A YouTube channel like that could provide quite a lot of money. You could also make money off this in many other ways - being an Internet celebrity pays. Not only that, but you could also get fame. And if you aren't seeking just money and fame, you could use the money you make for noble things.
