This program, while it is one of our simpler programs, is also one of the most powerful available. The Answer Checker allows you to determine which multiple-choice answer is correct for a given expression.
To use Answer Checker, you must first install the program, either by typing it into your calculator yourself, or, if you have a GraphLink, you can download and install it with the push of a button.
Once installed, run the program. "EQU=" will appear on the screen. Type in the equation given to you in the problem. Next, "A=" will appear. Enter multiple choice answer A. If this is correct, "YOU GOT IT" will appear, otherwise "B=" will appear. Continue entering answers until you get the right one. There are two Sample Problems at the bottom of the page, which you can use for practice.

Once again all hard to find buttons are explained in the Help Section, and if you are still stuck, hit 2nd, then 0, and you will be given a catalog of all hard to find buttons. |

To help you learn to use the Answer Checker program, we've provided these two real SAT sample problems:
37. (X^5+X^4+X^3+X^2)/(X^3+X^2+X+1)=
(A) 4X^2
(B) X^2 <- This is the correct answer.
(C) 4X
(D) X
(E) 4
23. (-3Y(X+2)+6Y)/(-XY)=
(A) -3
(B) -2
(C) 0
(D) 1
(E) 3 <- This is the correct answer. |
