90 + 78 - 1 is faster (to me). Actually, I believe it just depends on ways which either fits your brain or you gets used to it.

- dahart 10y agoFor this example, totally. What I'm talking about is more useful with larger numbers, when working on paper, and simply as an alternative way to think. I'm not making any claims about what's "faster", that's up to individual experience and preference. That said, rounding tricks get hard to use on 4+ digit numbers.
