Huh? While I essentially never have need to compute a square root by hand (unless it is a perfect square of course), shouldn’t one know how one would?

- radlad 1y agoWhy should one? Perhaps they should if it's relevant to their work, daily routine, or interests. But if they have no need for it?
- mattigames 1y agoNeeds are all fabricated, Ludwig Wittgenstein said "the limits of my language are the limits of my world", the same thing happens with logical thinking and all its tools including math.
- drdeca 1y agoWell, I think one should be able to come up with a way of doing so on the fly just from knowing that the square root function is monotonically increasing, and knowing binary search? Of course, doing it another way might be more efficient.
