(exponential, logarithmic, trigonometry, hyperbolic, etc.), as you would any real

or complex number. To demonstrate basic operations with algebraic objects,

let’s create a couple of objects, say ‘

π*R^2’ and ‘g*t^2/4’, and store them in

variables A1 and A2 (See Chapter 2 to learn how to create variables and store

values in them). Here are the keystrokes for storing variables A1 in ALG

mode:³„ì*~rQ2™ K ~a1 `, resulting in:

The keystrokes corresponding to RPN mode are: ³„ì*~r

After storing the variable A2 and pressing the key, the screen will show the

variables as follows:

In ALG mode, the following keystrokes will show a number of operations with

the algebraics contained in variables @@A1@@ and @@A2@@ (press J to recover

variable menu):

@@A1@@ + @@A2@@ ` @@A1@@ - @@A2@@ `

@@A1@@ * @@A2@@ ` @@A1@@ / @@A2@@ `
