Cool, a calculator user :)
This might be a start, although it's in Mathematica, not in Maple:
Sequence[2, 3] // Plus[##]&
Sequence[2, 3] // Times[##]&

The cool thing about RPN is that it eliminates the need for parentheses.
We can do this Maple thus:
`&+`, `&-`, `&x`, `&/`:= `+`, `-`, `*`, `/`:
3,4:&x%,7:&+%;
19
a,b:&/%,c:&-%;
a/b-c

The history is ALMOST what I've wanted:
O1:= 30;
O2:= 40;
O3:= O1 + O2;
70
I am without maple to test now... formatted... cd drive damaged...

RPN is cool because it "kills" the parenthesis.
