The Identity Property describes numbers that can be added or multiplied to other numbers without changing the values of those numbers.
Identities allow a term to maintain its identity even after addition or multiplication.
Perhaps you need to go back and make sure you understand the problem. If you keep trying, and vary your approach, you will get it. If you’ve ever played a video game or packed a suitcase for a long trip, you know that the order and placement of objects makes a difference in the outcome.
Take a second to step back and look it over with fresh eyes. Some things can be moved around to wherever they are convenient, while others can only go a certain way or they won’t fit.
Perform an operation on a number with an identity, and the result is the original number.
The Inverse Property involves addition to get to 0 and multiplication to get to 1.
