**Here's how you can use the Logic tool to add scores to answers or total up prices when creating quizzes, shopping baskets or order forms. **

To add a calculation:

**1.** Here is a Number question, asking how many of something someone wants.

Let's say each unit costs 5$, so I want the answer to this question to be multiplied by 5. Click **Logic**, then **Advanced**, and finally **Branching and calculations**:

**2.** A new window will open:

To add a calculation, click **Add logic**:

**3.** Now click the **If** dropdown menu, and select **Always**.

**4.** Now click the **Select...** dropdown menu, which will show the calculation functions available: Add, Divide, Subtract or Multiply.

Here we'll choose **Multiply**. Now we can choose our multiplication from the drop down menus. We will multiply the **SCORE variable** by the answer to the question "How many would you like?".

If you're using a **Payment** question, you will probably want to use the **@price** variable instead.

Click **Save** to finish setting up your calculation.

You can create as many Variables for your typeform as you want. This article explains more.

**5.** You can also choose to **Divide**, which looks like this:

**6.** When you choose **Add** or **Subtract**, the calculation changes as follows:

**7.** Changing the **Always** dropdown to **If** lets you create calculations for specific answers.

For example, here, if someone answers 10, I want to add 7 to the score. I might do this if I want to give people a discount for buying larger amounts, for example.

You can also add calculations to **Logic conditions**. For example, here is a Multiple Choice question. If someone chooses Car, then I want to add 50,000 to SCORE:

When you’ve finished adding calculations to a question, remember to hit **Save**, and you'll be returned to the Create panel to continue building your typeform.
