why are indirect proofs not taught in schools anymore?

Solution

Many students don\'t know what proof is. Many students don\'t realise it\'s actually about statements. Many students don\'t have experience in manipulating inequalities and divisibilities. Many students are philosophically uncomfortable with it. Many students find analogies unhelpful. Many students don\'t know what to focus on to come up with something to prove.
