Commutativity and associativity might sound the same, and indeed most commutative operations are also associative. But there are a few math operations that are only one or the other. Matrix multiplication, for example, is associative but not commutative Matrix multiplication - Wikipedia en.wikipedia.org/wiki/Matrix_multiplication#Non-commutativity . And surprisingly, floating point arithmetic — i.e. any math operator in JavaScript — is commutative but not associative Associative property - Wikipedia en.wikipedia.org/wiki/Associative_property#Nonassociativity_of_floating_point_calculation ! ↩

Last time we looked at the used electric vehicle market, it was to see what the options are if you're spending $10,000 or less. Two solid choices emerged quickly: a BMW i3 if you don't need much range, and a Chevrolet Bolt if you do. Lots of earlier Nissan Leafs made the list, too, but these had limited range and air-cooled batteries to contend with; we also included an assortment of compliance cars and, perhaps for the very brave, a Tesla. But what happens when you grow the budget by 50 percent? What EVs make sense when there's $15,000 burning a hole in your pocket?
