Question multiple conditions in if statements

Hi all, I'm confused about the proper syntax for multi-conditional if then statements. I'm trying to set limitations on info input on the command line.. i.e.

if [$x=[+|-|/|*|%]] ;then
$x=$vr1
else
print "You have entered an invalid option."

Can someone please clue me in on what is wrong with my syntax; what teh correct syntax is for using "and" "or" in similar statements.
