Job related though very rare to encounter
Able to compute 95% of different figures as long as it is below $1m (and in units of $100), below 20 seconds in the head (that's a buffer, actually it is 12 secs)
Been playing with ChatGPT with 10 sums and personally time it under 2mins but only managed to do it like 2 out of 10 times
Till last night,
Finished 20 sums in 4 mins, or at most in 260 seconds
The first one is wrong though the rest are correct
Initially I did it under 40secs per sum,then I discovered an easier and faster way to compute
There was a colleague who tested me in various multiplication (that is within the odds boundary of casino games), he was impressed though I was slower in 4995 of 11x (could have subtracted 55 from 55k)
Personally I'm not that fast,just that I have a good memory on short simple figures (2 digits * 2 digits)
Anything longer is not my forte though I can 3 digits * 1 digit decently
Now is to sharpen my accuracy to close the gap of perfection ,then next level is to practice 3 digits * 2 digits
