Hi,

I'm very new at maple and trying to understand its engine, but it is really hard sometimes when it doesn't make sense what it is doing. I have a function that gives me

com2(e,e,f)=eh+he

and then I would like to substitute eh into <1,0> and he into <0,1>, so I write

subs({eh=<1,0>, he=<0,1>}, com2(e,e,f))

which gives me the following answer

eh+he

Here comes the confusing part. When I plug in eh+he directly into the subs thing I get

<1,1>

Why are these two outputs different from each other? To clarify, why is subs({eh=<1,0>, he=<0,1>}, com2(e,e,f))=/=subs({eh=<1,0>, he=<0,1>}, eh+he)?
