Minimizing Cheating
There are many ways that you can minimize cheating. There are few steps you have to take to thoroughly check a calculator; but be assured, any calculator that goes through this check will be able to trusted.
If you want a calculator with absolutely nothing on it:
Press "2nd" and then the + sign.
Press "7".
Press the arrow key twice to tab over to "all".
Press enter.
Press 2.
Press enter.
Their calculator is now totally clear.
If you want to leave applications and programs but no "hidden information"; this is not really totally possible. There are two many programs that have a "teacher key" that looks like a regular program and are named innocently "area" or "circle", but store answers.
One good thing is to clear all the lists and to delete matrices and to clear all the y= lines.
