Simple operations with algebraic objects

Algebraic objects can be added, subtracted, multiplied, divided (except by zero), raised to a power, used as arguments for a variety of standard functions (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:

The keystrokes³„ìcorresponding*~rQ™to RPN mode are:K~a1`

After storing the ³„ì*~rQ`~a1variable A2 and pressing the key, the screenKwill show the variables as follows:
