How to draw on your calculator: 2nd > PRGM(DRAW) > Pen Press enter to turn pen "on" and enter again to turn pen "off"
Lines: 2nd> PRGM(DRAW) > Pen, then 2nd > PRGM(DRAW) > Line, Enter to set starting point of the line, enter again to set endpoint. (do not go directly 2nd > PRGM(DRAW) > Line, this will take you to the home screen)
Circles: Similar to lines. Press enter for center and end of radius.
Text: Similar to lines as well. Move cursor to the place you want to begin the text. Then type as you normally would on the home screen (2nd > ALPHA(A-LOCK) > *text goes here*)
Erasing: The tricky part! Took me half a year to figure this one out. Simply go to text and type spaces. This will be tricky because you have to erase in 1 x 5 blocks.
Clearing: 2nd > PRGM > ClearDraw > Enter
Storing Pics: 2nd > PRGM > right arrow > StorePic "StorePic" should appear on the screen and type a number after it, and press enter. You can store up to 9 pics.
Recalling Pics: 2nd > PRGM > right arrow > RecallPic "RecallPic" should appear on the screen and type the number of the picture you want to recall. Be sure to ClearDraw before you recall or the recalled pic will overlap with the current drawing.
But... what if my teacher makes me clear my RAM before a test? Archive your pics! 2nd > + > 2 > 8 > scroll down to the pic you want to save, and press enter. An asterisk should appear next to it. That means it is archived and will still be there after you clear your RAM. However if you wish to recall the pic, you must first unarchive it.
