LearnDash Arithmetic Quiz - Overview

The LearnDash Arithmetic Quiz add-on adds a new question type to your LearnDash quizzes, allowing you to create more elaborate mathematical evaluations.  The new “Arithmetic” question type” requires  students to solve for a variable by completing a formula.

Installation:

  • Install and activate the LearnDash plugin.
  • Install and activate the LearnDash Arithmetic Quiz Add-on.
  • A New Arithmetic Quiz menu will be added to the LearnDash menu.



Settings:

  • License:

You can configure your add-on’s license key from the “license” tab. Enter a valid license key in the corresponding field to receive automatic updates for this add-on. 

  • Configuring Arithmetic Questions:

Navigate to LearnDash LMS > Questions and add a new question. 

Configure the question’s options following this documentation. Then, select “Arithmetic” from the “Answer Type” meta box on the right and configure the rest of the question’s settings as demonstrated in the following example.

Example Question: 

“If a small soda glass contains [x] ounces of soda, and a large soda glass contains [y] ounces of soda, what is the total number of ounces in 4 large and 3 small glasses of soda?”

Now, if the admin selects a range of 1 - 5 for the variables, the random numbers will be displayed on the frontend against the variable from that range. Enter the same number in the Min and Max field if you want the variables not to be randomized.

This is how this question will be displayed on the frontend:

Using Decimal Points:

You can use decimal points in “Arithmetic” questions, so that answers will be calculated according to the specified number of decimal points.

You can set the number of decimal points to be used from the meta box that is  shown on the right side of a Arithmetic question’s edit page. If you would like to omit the use of decimals, simply check the “Disable Decimal Values for Answers” box.



This is how a question with answers set to three decimals will be displayed on the front-end:
