This class can multiply and verify numbers taken from forms.

It takes an array with values taken from a submitted form that takes two numbers and a result of multiplication and another for the sum.

The class verifies if the multiplication and sum are correct.

// If an answer has been posted, check that it is correct.

    // Instantiate the class passing in the post data as an argument.
    $test = new randomMultiplicationChecker($post_data);
    // Call the answerCheck method and create the variables $correct and $number_correct from what it returns.
