Her work focuses on mathematics and equity professional development, teacher leadership, and parent involvement. What does identity mean? In mathematics, the term identity has several important uses: An identity is an equality that remains true even if you change all the variables that are used in that equality. In mathematics, an identity function, also called an identity relation or identity map or identity transformation, is a function that always returns the same value that was used as its argument. Identity property of multiplication The identity property of multiplication, also called the multiplication property of one says that a number does not change when that number is multiplied by 1. . The identity function in math is one in which the output of the function is equal to its input, often written as f(x) = x for all x.
