That was a interesting read. Thanks for posting it here.

Quote:(…) it highlighted something I long ago realized: that many people — among them some school mathematics teachers — have a perception of algebra that mathematicians abandoned in the seventeenth century.

(…)

Yet I fear that not all school teachers convey just what a powerful tool it is — in part I suspect because they are constrained by a curriculum centuries out of date. Indeed much of current K-12 “algebra instruction” seems to go no further than the pre-modern algebra used prior to the 17th Century.

No surprise then, that the population at large views “algebra” as something different from the discipline that is taught universally in colleges and universities. Those Internet debates result from that division.

I couldn't agree more.
