# Calculations

Use Excel-style functions to perform dynamic, complex calculations that simple Conditional Logic wouldn't be able to handle within your forms. Easily add, subtract, multiply, lookup, cross-reference answers, and a lot more. This feature allows you to create smart and interactive forms that automatically calculate values or restrict inputs based on user's previous answers.
