∖ (set minus)

Computes a set difference.

Syntax

• A ∖ B

  • A and B are sets

Description

If A and B are sets, then A ∖ B is the set difference of A and B.

The ∖ operator is implemented by the SetDifference function.

Notes

To insert the set difference symbol ∖, type \setminus. (See Keyboard input.)

Don’t confuse the set minus symbol ∖ (U+2216: SET MINUS) with \ (U+005C: REVERSE SOLIDUS).

Examples

A ≔ { 1, 2, 3, 4, 5 }

{4, 5, 1, 2, 3}

B ≔ { 0, 2, 4, 6, 8, 10 }

{4, 6, 10, 2, 8, 0}

A ∖ B

{1, 5, 3}

B ∖ A

{6, 10, 8, 0}
