Question about todays minitest

Hello,

todays minitest contained tasks with binary addition with indices, like e.g +_4 or something similar.
I’m a bit confused, because this thread here “Chapters for the first minitest” explained that only material until (and including) chapter 1.3 would be relevant. But - as far as I know - this form of additions was content of the “1.4 - The Integers” chapter.

Am I missing something or was this actually no longer relevant to the test? I actually didn’t know what to do with the symbol either :laughing:

Thanks for your help,
David
