compareSets¶

Supported Response Area Types

This evaluation function is supported by the following Response Area components:

TEXT
EXPRESSION
MATH_SINGLE_LINE

Overview¶

Checks if a student's set expression matches the correct answer. Can compare both the meaning and exact form of set expressions.
Can also compare sets written in set notation containing elements, to see if the elements are the same.
When to Use For questions involving set operations like union (∪), intersection (∩), and complement.

Syntax¶

Operator	Meaning	LaTeX
`A u B` or `A \cup B`	`A union B`	\(A \cup B\)
`A n B` or `A \cap B`	`A intersection B`	\(A \cap B\)
`A'`	`A complement`	\(A^c\)

Examples:¶

"Express the union of sets A and B"
"Simplify: (A ∪ B) ∩ C"
"Write the positive integers less than 5 in set notation"

Parameters¶

is_latex (optional)

Default: false
Description: Set to true if students enter answers in LaTeX format (\cup, \cap). Set to false for plain text.

enforce_expression_equality (optional)

Default: false
Description:

false: Accepts any mathematically equivalent form (e.g., "A ∪ B" = "B ∪ A") true: Requires exact form match

is_set_notation (optional)

Default: false
Description: Set to true if students enter a response in set notation, e.g. {1,2}. Set to false if responses are named sets, e.g. A n B.
