PG problem file  Explanation 

Problem tagging: 

DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "contextInequalities.pl", "AnswerFormatHelp.pl", ); TEXT(beginproblem()); 
Initialization:
We must load 
Context("InequalitiesOnly"); Context()>flags>set(formatStudentAnswer=>'parsed'); $a = random(3,9,1); $ineq = "$a x \leq 10"; # TeX $answer = Compute("x >= 10 / $a"); 
Setup:
We require students to use inequalities by using
We use 
Context()>texStrings; BEGIN_TEXT Solve the inequality \( \displaystyle $ineq \). Enter your answer using inequality notation. $BR $BR \{ ans_rule(40) \} \{ AnswerFormatHelp("inequalities") \} END_TEXT Context()>normalStrings; 
Main Text: 
$showPartialCorrectAnswers = 1; ANS( $answer>cmp() ); 
Answer Evaluation: 
Context()>texStrings; BEGIN_SOLUTION ${PAR}SOLUTION:${PAR} Solution explanation goes here. END_SOLUTION Context()>normalStrings; COMMENT("MathObject version."); ENDDOCUMENT(); 
Solution:
