# Creating Arithmetic Questions (2+2)

Arithmetic questions (2+2) enable you to assess students' knowledge and comprehension of mathematics and number theory. Ensure each respondent receives a unique question by including set variables that randomly generate numbers within the problem.

For example, if variables x and y have a min value of 0 and max value of 6 with a step value of 2. Variables for each student will be randomly selected from (0, 2, 4, 6). For the equation {x} + {y}, one student may see 2 + 6, and the next student may see 6 + 6.

Here are the steps to create an arithmetic question:

- Access a Question Library or Quiz
- Create an Arithmetic Question
- Enter Question Details and Save
- Enter the question text
- Define the arithmetic formula
- Define the variables
- Provide hints and feedback (optional)

## Step One: Access a Question Library or Quiz

Questions can be created in a Question Library or Quiz. For a Quiz, it is recommended to first create questions in the Question Library, then import them into the Quiz. For additional information see the following guides, then return to take the next step:

- Option 1: Creating Questions in the Question Library
- Option 2: Creating a Quiz (new interface)

## Step Two: Create an Arithmetic Question

1. From **New** select **Arithmetic Question (2+2).**

## Step Three: Enter Question Details and Save

### Enter the question text

1. Fill in general details such as:

**(a) Title**: is used for searching or later importing into a quiz.- Assign
**(b)****Points**for the fill in the blanks task. - Enter
**(c) Question Text.**Ensure each variable must be contained within**curly braces { }**. - (d) Optional: Choose a
**Difficulty**level from the dropdown list or choose to**Insert an Image**to upload an image to accompany your question.

### Define the arithmetic formula

2. Next,

- Enter your arithmetic question
**formula**. Ensure each variable must be contained within**curly braces { }**.- For example: What is the sum of {x} and {y}? Your formula would be {x} + {y}, which will take a random value for the x variable + with a random value for the y variable.
- See
**create arithmetic questions**, by D2L for a list of supported operations, functions, and constants.

- Optional - Refine answer criteria: You can use
**Answer Precision**to control how many decimals points students should enter,**Tolerance**to accept a given range of answers from students, and then select**Evaluation Option**.

### Define the variables

3. Define mathematical Variables such as:

- Give each variable a
**Name**(e.g: x), a minimum value in**Min**, and a maximum value in**Max**. The system will later generate a random number within this range. - Enter
**Decimal Places**to select the applicable number of decimal places for the variable to have. **Step**: sets increments for the min and max values when choosing your variables.- For example, a step value of 2 would only choose variables that are increments of 2 such as 2,4,6,8,10.

- To add more variables, select
**+Add Variable**.

- Give each variable a

### Provide hints and feedback (optional)

4 (Optional). You can provide students with hints to help them answer the question, and enter feedback to show students after they have completed the question. To do so, select **Expand question hint** or **Expand question feedback**.

5. When complete select one of the save options

**Save**– save the question and return to the question library, quiz or survey**Preview**- view how the question will be displayed to students**Save and New**– save the question, then create a new question**Save and Copy**– save the question, then create a copy of the current questions
