About this calculator
Overview
Set Union evaluates Set Union for the math / sets-logic library. Primary input cue: Set A [required] — field id `setA`. Method anchor: A∪B.
When to use
Reach for Set Union to compare scenarios by changing one input at a time for set union.
Inputs explained
- Set A [required] — field id `setA`
- Set B [required] — field id `setB`
Formula / method
A∪B (calculator id: set-union-calculator).
Worked example
Worked values: setA = ['1', '2', '3'], setB = ['3', '4'] → result = ['1', '2', '3', '4'], cardinality = 4
Interpreting results
If set union looks implausible, re-check units and which field is optional vs required.
Assumptions
- Empty required inputs are not silently replaced with zeros for set union. [set-union-calculator]
- Set Union is computed only from the fields you enter on this calculator.
- Real-number arithmetic is used unless set union explicitly needs integers.
Limitations
- If multiple conventions exist for set union, this calculator uses the convention implemented in its engine path.
- This page does not provide a full textbook proof for every identity related to set union.
- Complex/branch cuts and undefined points are not always interactively annotated for set union.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
