Математические операторы () — блок стандарта Юникод. Содержит символы для математической, логической и множественной записи.
Знаки плюс (+), минус (-), равно (=), больше (>) и меньше (<) чем имеются в блоке Основная латиница. А знаки плюс-минус (±), умножение (×) и деление (÷) имеются в блоке Дополнение к латинице — 1. Для отделения от дефиса решили добавить отдельный знак минуса в позиции U+2212 (−).
