Open the Function aplet. Select Function 2. Highlight the line you want to use, and enter the expression. (You can press to delete an existing line, or CLEAR to clear all lines.) 2 CHARS ≤ 1 CHARS > AND 4 1 CHARS ≤ 1 CHARS > 1 Note: You can use the menu key to assist in the entry of equations. It has the same effect as pressing . 3-12 Function aplet
