What is another word for equal sign?
Pronunciation: [ˈiːkwə͡l sˈa͡ɪn] (IPA) 
The equal sign is a fundamental mathematical symbol used to show equivalence between two values or expressions. However, there are other terms used to represent this symbol colloquially, including balance mark, double-harpoon, double-sling, twin-harpoon, and tie sign. The balance mark is attributed to the way it represents equation balance, whereas the double-harpoon and double-sling refer to the symmetrical shape of the symbol. The twin-harpoon and tie sign refer to the appearance of two parallel lines that seemingly connect or join equal components. Although these synonyms may not be as commonly used as the equal sign, they add diversity and creativity in mathematical communication.
