Solving equations with one unknown through NUM.SLV

The calculator's NUM.SLV menu provides item
types of equations in a single variable, including non-linear algebraic and
transcendental equations. For example, let's solve the equation: e
0.
Simply enter the expression as an algebraic object and store it into variable
EQ. The required keystrokes in ALG mode are the following:
Enter a comma
Enter name of variable PYR
Enter a comma
Enter name of variable FV
