Lesson 9: Arithmetic with Symbols

Arithmetic using syml:)olic variables is very nnich like arithmetic using

numbers. You can make symbolic calculations on the stack the same

way you make numeric calculations-..........except you use algebraic objects

(and tick-mark delimiters) instead of just numbers.

Example: I'se symbolic math to create the equation j/ = 1 — c

Step 1: Enter y and the number 1.
