Maths standard of an 8 year old

June 1st, 2021, 8:48 am

This is my son wirting out 8^n and 9^n from his head, I think self taught, and yes he is on the spectrum. What do you think? The 9^n sequence has one error in it carried through.

Can he do [$]e^5[$] to two decimal places accuracy?

To see if he will become an accountant or a Fields' medalist, see how he handles Gauss's problem: 1 + 2 + ... + 100

the right answer to this is someting like =nx*0.5+nx?

I havent studied maths since 18, I was better at Chemistry

Any other sequences that I can show to him appreciated. I will post the effort he makes.

Had he a better handwriting, he wouldn't have made en error at 9^10. I guess he misread his own "6" for "0" ;-)
He might like calculating the pi number in memory.

A couple more. The second power of five goes to a 1 followed by zeroes number in the end so I guess he worked it backwards as another division of five is not a whole number
