most common question asked in a maths classroom: "why do we have to do this why can't we just use a calculator"
blatant lie told to every pupil since like 1980: "you won't always have a calculator available"
actual truth: "calculators are devil objects, none of them work the same, you'll only really be acquainted with how exactly one of them works across your lifetime and when it comes time to use it again you'll have forgotten how it works anyway"
@MililaniVF (1/3) When I was 16, my mother was building a house in the middle of nowhere. To set cinderblocks for the foundation, we measured the sides and then the diagonals to verify the foundation was square. The diagonal needed to match the Pythagorean theorem, a^2 + b^2 = c^2. One day at the house site 10 miles from civilization, neither of us had a calculator. Despite being shown how by my mother more than once, I still cannot remember how to calculate square roots by hand.
