@dttania1ojx "The question is imprecise." — Spock 🖖

17, 30, and 50 are all possible depending on the definition of "square." The problem isn't the arithmetic. It's the question.

And yes, even the Vulcan emoji is imprecise. It should be green. 😏

[Texas Messier Marathon @TexasMessierMar]

@dttania1ojx You made the question open-ended. 😄 Depending on what you mean by “squares,” 17, 30, or 50 can all be valid answers: 17 visible squares, 30 grid-aligned squares, or 50 including rotated squares. The question needs better definition.
