HP 50g manual Creating variables, Algebraic mode

To unlock the upper-case locked keyboard, press ~.

Try the following exercises:

~~math`

~~m„a„t„h`

~~m„~at„h`

The calculator display will show the following (left-hand side is Algebraic mode, right-hand side is RPN mode):

Creating variables

The simplest way to create a variable is by using the K. The following examples are used to store the variables listed in the following table (Press Jif needed to see variables menu):

Name	Contents		Type
α	-0.25		real
A12	⋅	5	real
	3 10
Q	‘r/(m+r)'		algebraic
R	[3,2,1]		vector
z1	3+5i		complex
p1	<<→ r 'π*r^2' >>		program

Algebraic mode

To store the value of –0.25 into variable α: 0.25\K ~‚a. AT this point, the screen will look as follows:

Press ` to create the variable. The variable is now shown in the soft menu key labels when you press J:
