implicit multiplication fails - compsystems - 04-20-2016 02:13 PM
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?

The convention of putting a constant to the left side of its literal multiplicand seems to work:
(I think I've read somewhere that implicit multiplication is not completely supported, though)
[CAS]
8x => 8*x
[+/-]8x => -8*x

Hello,
Implicit multiplication is (partially) there to please some math teachers so that they can type 3A or something like that.
However, using it should be Highly discouraged as it is a sure recepie for disaster.
