The calculator automatically inserts * between a number and an
alphabet letter (a-zA-Z) and between and number and a (.
It also automatically replaces - followed by a letter or ( with
-1* . This will allow most algebraic expressions in an intuitive
way. However avoid putting spaces in your expression or odd
things may happen.
