Hi

CAS MODE:

3x -> 3*x ok

x[-]8 > x-8 ok

[+/-] 8x -> -8*x ok

x*[+/-] 8x-> -8*x ok

but

x [+/-] 8 -> Syntax Error

x [+/-] 8 -> x*(-8) or -8*x ok

simulated prime (PC COMPUTER SOFTWARE):

the [-] key on a keypad placed [+/-], I think we should put [-]

x [+/-] 8 -> Syntax Error

[-] -> ANS-

...

you agree?
