This is what I do, except I would add 700 and 236 at the end.

Well except I would probably add 700 and 116 or something, because my working memory fucking sucks and my brain drops digits very easily when there’s more than 1

I might. Then I can subtract 74 to get 74*14, and subtract 28 to get 72*13.

I don’t generally do that to ‘weird’ numbers, I usually get closer to multiples of 5, 9, 10, or 11.

But a computer stores information differently. Perhaps it moves closer to numbers with simpler binary addresses.
