Re: [Phys-L] problems with the teaching of algebra

As another wrinkle, we often teach students that it is "best" to always use "standard" units.  Eg if you measure in m, kg, and s, your answers will come out in N, J, & W.  So if you want your later calculations to come out in "appropriate" units, measuring in meters is most "appropriate"!
