    I loved the video. I haven’t thought it all the way through, but it seems like a very persuasive argument for better notation. There should be (probably is) a website that catalogs all such notation and vocabulary blunders in mathematics. The fact that the negative sign and subtraction sign look so similar should be on there. Also renaming the “complex” or “imaginary” numbers.
