ESC to enter normal mode (if you’re in a different mode like insert) : (colon) to enter commands q to quit ! (or a) to use the quit command withiut keeping any changes
Joke aside, it’s not taught as 4 × 20 +10 but simply “90 is pronounced quatre-vingt-dix” — which kinda is a mouthful, but you rarely count to 90 as a kid anyway.
For a serious reoly, I think the expression “If they have eggs, buy two” is redundant. If they didn’t have eggs, the kid just can’t and won’t buy any eggs.
I think the proper command would be, “Please buy 1 bottle of milk and two eggs.” That way, the kid won’t be confused and it’s still a proper valid command.
Unfortunately though, the sentence is ambiguous even to non-programmers. It is unknown whether the if condition applies to
buying two eggs (buy two eggs)
buying two bottles of milk (buy two bottles instead)
