The minus-or-plus sign (∓) is a mathematical symbol that serves as the exact counterpart to the more common plus-minus sign (±). It is primarily used in complex formulas to indicate that a secondary expression must take the opposite sign of the first. For example, if an equation features ± in one section and ∓ in another, picking the plus for the first means you must use the minus for the second.
