When you say "base 10", is that "10"-er written in big endian or small endian?

It's as if there's a convention of sorts to how we write numbers (regardless of base).

If you don't state endianness in your exercise, one should assume the convention is followed.

That makes no sense. The value of two bytes as a single number is strictly dependent on endianness, and there's no "convention" that can be assumed.
