Hi,
I am a maths enthusiast myself, unfortunately, I end up doing medicine instead( societal pressure), I think you are cool.

...that problem with the multiples of 4 in Fibonacci series lends itself nicely to explorations of congruence math, e.g., finding # of multiples of 3, 5, 6, 7, etc...., all by adding up remainders each time!

Any way u can explain vietas jumping formula and use it to explain 1988 imo Q. 6

...Rather more involved would be same problem with number of multiples of five among the first 1000 terms of Fibonacci Sequence, as the 'blocks' of units' digits repeat in chunks of sixty...!

Beginning, you only needed the first digit, realize that BEFORE you square a four digit number!
Anyway, very funny, great video, and costume

...wow, ...I was laughing and laughing as Richard discussed 'doing something stupid' and began to multiply 2013 by itself many many times, really really goofy! wow!

Nothing wrong with the solution but the explanation was kind of repetitive. I just wanted to get on with it. Still, I love these vids!
