# What is a variable in WhatsForm?

Variables are used in the Calculation Component to access the answers to
questions in your form. In order to add values to your calculation from
different questions, you have to use variables.



Variables are basically anything that you access using the @ symbol, which is
only available within the Calculation Component
[https://whatsform.com/help/article/1109-calculation-component]. You can either
type @ or click on the corresponding icon to select variables.
