*Introduction

So you’ve created a quiz, and you want to use Arlinear’s math suite in order to build math questions for your students.

In this article, we will cover building different math questions and using randomized variables within your questions

*Create a Math Question

Start by creating a math question by hovering over “+ Add Question” and clicking “Math”

*Compute Operations 

Compute Operations require the student to calculate the answer to the defined math question.

Let's start with an elementary example problem, "what is 1+1". 
 

1. Click on “+ Compute Operation” and type 1+1 in the box.

Pro Tip: When interpreting math, Arlinear accepts a wide variety of inputs. Try typing “1 plus 1” or even “one plus one” .

*Solve for X

The “Solve for x” problem type is very common for a variety of subjects. Let's start with a very simple example. 

1. Click “+Solve For Variable”.

2. Type “x^2+5x+6” into the left side of the equality, and “0” into the right side.

Hint: The “^” symbol means “to the power of”. So typing “x^2” will give the same results as typing “x squared”

We want students to find all values of x, so set the value of the drop-down to “equal to”

*Variables

Defining variables in the quiz builder works the same as in mathematics.

1. Create a variable a by clicking “+ Variable”, then set its value to 2. The variable can be placed in any following math entry.

2. Click the “Random Integer” button to make your variable a random integer. For each student, your variable will take on a different value. Let's make a   random variable between 1 and 5.

Pro tip: "RandomInteger[{1,5}]" gives a number between 1 and 5, try changing the 1 and 5 for different results.

*Previewing your quiz

1. Set the value of “Check Answers Available” to 3, and click “Preview Quiz”

2. Now you can see your quiz as students would see it. Type in your answers and click “Check Answers” to see Arlinear’s auto-grading capabilities.

3. When you have a random variable in your question, refreshing the page will cause its value to change.

*Conclusion

And that’s it! That’s how you create and automatically randomize your math questions in the Arlinear Quiz Builder. Feel free to drop a comment with a question and we’ll happily answer it for you :)
