- fjdlwlv 9y agoThese "proofs without words",that are algebric proofs ith a little illustration,don't deserve the name. Most elementary arithmetic don't use words, they is arithmetic.a good proof without words lays out all the pieces of a problem more compactly than the arithmetic derivation -- for example a proof of Pythagorean theorem that is just a square with lines drawn across it.
