Consider this is part 3 of chapter 58. Usually the reveal is done after 3 or 4 chapters after introductions, so...how many more chapters to reveal that he is a she.
I mean it's pretty much one of the ways to prove the Pythagorean Theorem, no? It's just that they fill in the variables and calculate, rather than directly going to the solution: (a+b)(a+b)-4*(a*b/2)=aa+bb+ab+ab-2ab=aa+bb, so cc=aa+bb.Interesting take on the usual "MC has advanced knowledge" trope; instead of portraying the natives as idiots, it actually went the logical route and invented a different method to arrive at the same answer.
Though, it does make me wonder if that other method actually works.

It's funny because I thought the same thing, "I need to try that." Turns out, it's just the basic "proof of Pythagorean theorem" which, amusingly enough, is just Pythagorean theorem. Heres a link to youtube showing how it breaks down. www.youtube.com/watch?v=VjI4LtotC2oInteresting take on the usual "MC has advanced knowledge" trope; instead of portraying the natives as idiots, it actually went the logical route and invented a different method to arrive at the same answer.

I think there's merit in the simplification.It's funny because I thought the same thing, "I need to try that."

But yeah, just breaks down to exactly what Yuuji said. Which means the professors of this world already created Pythagorean theorem and thus should NOT have been impressed with Yuuji's simplification.
Based off the explanation, they must have though. They made the outer square, subtract the 4 triangles to get the area of the inner square, and got the side based off the area of the inner square. They are quite literally, finding the root of a square from the area.They don't know about the square root operator, not the theory itself.
