**Note:** Before we get started, take a moment to familiarize yourself with our tutorial on setting up templates with conditional logic found here

In This Tutorial Youʻll Learn:

## STEPS

### Simple Math

1) Add some **integer** or **decimal** questions that you want to use for a calculation

2) Add the question that you want to use to show the final number

3) Click the **Conditional Logic** tab then click **Add Rule**

4) Fill in the **Results** field with the equation

*If you need help click the **(?) **to show hints

5) Hit **Save**, then **test** your survey to make sure it's working correctly

### Math Including Specific Numbers

Let's begin by setting up a sample template to convert Celsius to Fahrenheit. The equation that we need to set up looks like this: C x 1.8 + 32 = F.

1) Our first question will be where we input the temperature in celsius. To do that simply add a question, add a **label**, set the type to be **decimal**, leave the **default value **blank.

2) Next we need to add a question that will show the result we are expecting. Add a **Question**, set type to **Decimal, **then click the **Conditional Logic** tab to set up your expression

5) Click **Add Rule**, then click within the **Result field** to see a dropdown list that will let you arrange your expression with all the **integer/decimal type **questions within your template. For the numbers, you can begin typing then press **Create** to make a number "button".

**Note: **You can click the question mark icon by **Result** to see sample equations

6) **Save** your template and head over to its dedicated **survey** to test it out! If you followed this tutorial correctly, you should see the math doing its work. For example, I entered 27º in our celsius input box and was returned 80.6º in fahrenheit.

### Repeating Sections: Sums and Averages

You can use the math features to sum and average **repeating section** number totals.

For this tutorial we will use the example of creating a work hours log to enter individual hours worked by staff on a specific day.

1) Add a **Section** then set the **Repeating limit**

**Example:**A section called "Work Hours" that repeats 10 times

**2) **Add a **integer** or **decimal** type question within the section

For our

**example**we added "Hours" as a**decimal**type question

3) Add **another section,** then **add questions that require math**

For our

**example**we created "Totals" as the new section and added two questions that will use the entires from "Work Hours" to do math

### Section Total: SUM

Now that we have our sections and questions set up...

1) Add** conditional logic** to the questions that is asking for a **sum**

For example,

**Total Hours**needs to add all "**Hours**" entries togetherTo get a

**sum**, the expression in**Results**is**SECTIONSSUM ( Hours )**

### Section Total: AVERAGE

1) Add** conditional logic** to the questions that is asking for an **average**

For example,

**Average Hours**is asking for the average of all the "**Hours**" entriesTo get an

**average**, the expression in**Results**is**SECTIONSAVG ( Hours )**

2)** SAVE** the form

### Test your math!

**1) **Go to** **your survey and add a **new entry**

**2) Enter** multiple entires in your repeating section to see the math in action

In our example, "Total Hours" and "Average Hours" automatically update as you add entries to the repeating section
