Re:Too Many symbols

Start up EasyC, Press F1 (for the Help)
Double Click “Programming” in the Left Pane, then Double Click “Project Setup” (in the Left Pane), then Click on “Commonly used operators” and read & Print (if desired), then click on “Table: Arithmetic Operators in Order of Precedence” (and read & Print [if desired]).

You might also find clicking on “Variable definitions table” helpful too.
