Hello Calcs
There might be a typo in the (info "(calc) Basic Algebra Tutorial").
It says in the third input example ("(18 - 2 y) x^2 - 6 x^4 + 6 y" is on
the stack):
1: 17 x^2 - 6 x^4 + 3 1: -25
. .
1:2 s l y <RET> 2 s l x <RET>
But I think the first input should be "' 1:2 <RET> s l y <RET>".
What do you think?
Dieter

Actually an input "1:2 s l y <RET>" is working without switching to the Algebraic mode first, Calc is so damn good! I'm sorry for the noice Dieter -- Best wishes H.

Another example "1 <RET> 2 /" is the same as "1 <RET> 2 <RET> /". If you're entering numbers then commands are recognized immediately. If you're in algebraic insert mode, started with an ' then letters are part of the input. You learn this with experience.
