The identity, i, is a member of a set which, in the context of a mathematical operation, has the property that for every element x in the set:
x @ i = x = i @ x
For real numbers, if you take @ to be addition, the identity is 0.
If you take @ to be multiplication, then the identity is 1.
principal(in terms of math)- the amount you borrow or deposit
