In this video, we’re breaking down the subtraction operator and the sign operator in Power FX, both represented by the minus sign (-). The subtraction operator helps you calculate differences, adjust values, and even manipulate dates, while the sign operator lets you define and work with negative numbers.

We’ll start with an easy example of subtracting two numbers, then move to Power Apps to show how to calculate discounts or track remaining budgets dynamically.

Finally, we’ll jump into Copilot Studio to see how the minus sign is used to work with variables and handle negative values effectively.
