Which equals 29^2 x .01 => ((28 x 30) +1) X .01
=> (840 + 1) x .01 => 8.41
28 x 30 is an easy mental calculation, as is adding 1, as is moving the decimal place over 2 places. I am teaching this to 4th graders, in two weeks. % to decimal is next week. They can square 2-digit numbers in their heads, already.
Reminds me of boxed software, too. You check the compatibility, the features that included one must-have new feature. Buy it and discover what vaporware is. It started me on the ethics of pirating, finding out if it actually works, and then, and only then, buying a real copy. I donate to developers on Linux, now.
This doesn’t ask your question, but this may be of useful to people, anyway.
I’ve just joined ground.news, a pay site. The great part about this site is that it rates news as to left, center, or right leaning, and rates the “factuality” of the sites. Filtering out non-factual knocks out a large part of the outlier’s lies, and shows who the people are, who push them. like knowing the players pushing their agenda. One caveat is that some that push lies still slide through by quoting the people who spout lies without disclaimers of the reliabilty of their false claims. One rule of thumb that I find helpful is that I mentally filter out any pleas to emotionalism. Manipulating readers/viewers emotionally is the opposite of informing. Sites that try to be centrist and ignore whether the sources are reliable about facts, end up being half lies or propagandsa. It is useful to keep in mind that blatently propaganda sites work in some truth to give themselves some plausibility. Only the highest reliable news are worth letting in to your news sphere.
This is a worldwide problem as paid propagandaists muddy the news sphere. Welcome to our cyber warfare world.

Where do you go on Lemmy for reliable news and politics?
I’m enjoying Lemmy so far, for the most part....
