Thanks Mr.ronjonp.
+ , * of that lisp works for me.
But -(minus) , /(division) doesn't works for me.
When I commanded - or / function, It showed me a massage, "error: bad function: xxxx"
And When I command +(add), I can't command continually just by a spacebar.
I'd like to command the previous command(add) just by a spacebar.
