Re: Teaching Kids to Code

If I can put my 2c in, as an Australian high school computing teacher... Coding, as in Software Development, is an option within the IST elective in Years 9 and 10 (out of 12) in the NSW curriculum.

Re: Designing a function

(2^x)/7 is about that. You could probably do something with a scale on the x too. Although after playing with it (ie telling wolfram alpha to solve it) it doesn't look very nice. Another option is to find a function f such that f(10)-f(0)=210 and take the derivative. The integral of 2 x /7 from 0 t...

Re: "these ones"

Sydney, Australia (not Canadia) and "these ones" sounds perfectly acceptable. In fact, just saying "these" doesn't sound emphatic enough.

The sum of the proper divisors of n - n, assuming you start at n=0. Meaning the n=28th term should be 0 (as it is perfect).

Re: Favorite number sequences?

My favourite sequences are ones that can't be fully defined. For example, A(n) = An(n)+1 where An is the nth sequence in the OEIS.

A = 2, 3, 2, 1, 3, 4, 1, 7, 7, 5, ...

Ironically, this sequence is A102288 (https://oeis.org/A102288), which means that A(102288) is undefined!
