Add

What It Does

Adds two numbers together to produce their sum. It's a basic math operation useful for combining numeric values like spacing tokens or opacity percentages.

Inputs

Name	Description	Type	Required
a	The first number to add	Number	Yes
b	The second number to add	Number	Yes

Outputs

Name	Description	Type
value	The sum of a and b	Number

How to Use It

1. Drag the Add node into your graph.

2. Connect a number (like 3) to the "a" input.

3. Connect another number (like 3) to the "b" input.

4. Run the graph—your output will be 6.

Tips

• You can use the Add node with token references, like adding a base spacing value to an increment.

• For adding more than two numbers, chain multiple Add nodes together or use the Variadic Add node.

• Subtract: For removing one number from another.

• Multiply: For multiplying numbers together.

Use Cases

• Spacing Calculations: Add a base spacing unit (4px) to a multiplier to create consistent spacing increments in your design system.

• Opacity Adjustments: Add a percentage to a base opacity value to create a range of transparencies for different states.

• Font Size Scaling: Add a fixed increment to your base font size to create larger heading sizes.
