PG problem file Explanation

Problem tagging: 

DOCUMENT();

loadMacros(
"PGstandard.pl",
"MathObjects.pl",

);

TEXT(beginproblem());

Initialization: 

Context("Numeric");

$f = Formula("3^(-x)");

@answer = ();
foreach my $i (0..2) {
  $answer[$i] = $f->eval(x=>$i);
}

Setup: We create an empty array @answer and use a foreach loop to simplify filling it with values. 

Context()->texStrings;
BEGIN_TEXT
If \( f(x) = $f \), fill in the table of values with numbers.
\{ AnswerFormatHelp("numbers") \}
$PAR
$BCENTER
\{ 
begintable(5) .
row( "\(x = \)", "0", "1", "2" ) .
row( "\(f(x) = \)", ans_rule(5), ans_rule(5), ans_rule(5) ) .
endtable(); 
\}
$ECENTER
END_TEXT
Context()->normalStrings;

Main Text: Notice that the table is inside a Perl code block \{ \} and that there are periods at the end of each line (after each of the subroutines begintable(num cols) and row( )) except for the last line. These periods are Perl's string concatenation operator. 

$showPartialCorrectAnswers = 1;

foreach my $i (0..2) {
  ANS( $answer[$i]->cmp() );
}
