Is there a mathematical property for a value which when applied to some function doesn’t change the result of the computation?

For example 1+ 3+ 0 = 1+3. 0 is “that” value here.
Example 2-> 3*4*1=3*4. 1 is “that” value here.

"Identity (element)".

0 is the additive identity. 1 is the multiplicative identity.

@jztusk ah, thank you!
Is this related to the identity function or is that something else?

@the_lazy_folder @jztusk the identity function is the identity element for function composition.

@chrisphan wow. That is beautiful
