1. The answer is 120 which is 5! or 5 factorial. This is an easy one, yet….
2. pi = 4? gave up.

The first one: so the answer as already pointed out is NOT 5 but 120, which is 5 factorial, or 5!
The second one is again basic differential calculus. If you continue the process of replacing the edges of the square progressively with smaller squares, in the LIMIT tending to infinity, you will NOT end up tracing the circular path of the circle’s arc. You will end up with a straight line that is tangential to the circle. In other words you would have basically taken a square, and created another square that is the same square simply rotated by 45 degrees. And yes, the perimeter would still be 4. If you wanted to trace the arc of the circle, you cannot follow this process. You will have to circumscribe the circle with a square, then a pentagon, then a hexagon etc, and in the limit you will have an infinite sided polygon with every side tangent to the circle. When you do that you’ll see that the area changes every time you change the number of sides of the polygon, until you get pi times r^2, where r is half the side of the original square.

Every vertical drop still ends on the circle at its bottom at every stage. As the horizontal lines shrink to zero, The top of a vertical drop coincides the bottom of the earlier vertical drop which lies on the circle.

I will sleep better tonight as a result of this explanation. Never could have figured it out myself. Thank you!

Oh don’t apologize! I enjoyed it – even if I was out-foxed. 🙂

If one follows normal rule for solving the equation, then the answer is 120 or 5!. But if we follow our L to R logic then answer is 5.
π = 4 is interesting
