💡𝚂𝗆𝖺𝗋𝗍𝗆𝖺𝗇 𝙰𝗉𝗉𝗌📱<p>6/6<br>So remember, the "M" for multiplication in the mnemonics (BEDMAS, PEMDAS, whatever) refers LITERALLY to multiply signs. If there's no multiply sign, then it's NOT "multiplication", it's a Term. If there's a bracketed term which has a coefficient, then the coefficient has to be distributed, and that's part of solving Brackets/obeying The Distributive Law. Anyone who says anything different to that is just <a href="https://dotnet.social/tags/LoudlyNotUnderstandingThings" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LoudlyNotUnderstandingThings</span></a></p><p><a href="https://dotnet.social/tags/MathsIsNeverAmbiguous" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MathsIsNeverAmbiguous</span></a> <a href="https://dotnet.social/tags/DontForgetDistribution" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DontForgetDistribution</span></a></p>

💡𝚂𝗆𝖺𝗋𝗍𝗆𝖺𝗇 𝙰𝗉𝗉𝗌📱<p>3/7<br>I've even seen one say (of calculators) "sometimes it obeys (IM), sometimes it doesn't". That's because the calculator in question obeys Terms but NOT TDL, and it's behaviour is 100% consistent with that (but confusing to someone who has lumped them together as IM). They even went as far as claiming "PEMDAS is wrong", cos they were treating it like rules (whilst also <a href="https://dotnet.social/tags/LoudlyNotUnderstandingThings" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LoudlyNotUnderstandingThings</span></a> like the actual rules TDL and Terms), and made up a new mnemonic, so let's look at mnemonics...</p>
