Question

The identity element for addition in integers is 1 ? why ?

Answer 1

Answer:

more formally, an identity element is defined with respect to a given operation and a given set of elements.

Answer 2

Step-by-step explanation:

More formally, an identity element is defined with respect to a given operation and a given set of elements. For example, 0 is the identity element for addition of integers; 1 is the identity element for multiplication of real numbers

For example, 0 is the identity element under addition for the real numbers, since for any real number a, a + 0 = a, and 1 is the identity element under multiplication for the real numbers, since a X 1 = a.
