# Simple Calculated Questions

Simple calculated questions are individual numerical questions based on a formula using variables or "wildcards" (i.e {x} , {y}). These wildcards are based on a set of pre-generated values making it possible for respondents to see different values for the same question.

Example of a Simple Calculated question: 1. In the ?Question Bank, ?select the desired question category, then click ?Create a new question... and select Calculated simple and click Next?. The ?Adding a question? screen will open.
2. Give the question a descriptive name - this makes it easy to identify it in the question bank. The question name is not visible to students.
3. Enter question text, include any wild cards (variables) surrounded by curly brackets (e.g., {b} and {h}).
?Example: `What is the surface of a rectangle in square meters with a base of {b} m and a height of {h} m ?`
4. Enter the Correct answer formula ?using the same wild cards as the question text in order to define how a correct answer will be calculated.
?Example: `{b}*{h}`
After creating a question, be sure to check to make sure the question works correctly. Click the magnifying glass icon next to the question in the Question bank? to view a preview of the new question.
