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 multiplechoice 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.



Press the PRGM button, then press left to go to Create New. Press enter. Then "Name=" will appear. The calculator runs the Alpha mode, enabling you to type letters. 

Using the keypad type in the letters ANS, then press enter. Then type in the program below. Cant find some of the keys? See the Help Section. 

Keep in mind, all bold and italicized words can not be typed in letter by letter. For example, Str1 can only be entered by hitting the VARS button, then 7, then enter.


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. 




3>X
5>Y
0>B
"A=">Str1
Input "EQU=",P
Lbl 1
Input Str1,A
If P=A
Then
Disp "YOU GOT IT"
Disp Str1
Stop
End
B+1>B
If B=1
"B=">Str1
If B=2
"C=">Str1
If B=3
"D=">Str1
If B=4
"E=">Str1
If B=5
Stop
Goto 1



To type letters press ALPHA, then the letter. 

> is the Store button located directly above the On button. It looks like STO> 

Str1 is found by press VARS, then 7, then enter. 

Input is found by pressing the PRGM button, then right, then enter. 

Lbl is found by pressing the PRGM button, then 9. 

If is found by pressing the PRGM button, then enter. 

Then is found by pressing the PRGM button, then 2.

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.
