We ought to purge the division operator from the curriculum. Let's be honest, it shipped broken, it enforce sequential evaluation where order ought not to matter. Free your notation system from the tyranny of rule, and multiply fractions in whichever order you like." 40 / 10 * 2, a kludge.40 2/10, timeless, classic, parallel.40 5^-1, if fractions are not your thing. "Big Arithmetic has played us for absolute fools. Now, don't even get me started on subtractions, get rid of that bloat, add negative numbers if you need to, but do not ever subtract.https://wiki.xxiivv.com/site/now:bloat:

@neauoireI agree. Algebras are defined by a multiplication and an addition, all the rest is derived and should be implemented as simply as possible. If the algebra is commutative it is silly to introduce noncommutativity for operational reasons.. afaiac@yngmar

@neauoire My math teacher used to say "Brüche sind unsere Freunde" ("fractions are our friends").

@neauoire Alternative, abandon PEMDAS and chew threw everything as a string. Who needs a tree of terms when you can slurp a noodle.
