Inverse Operations
Operations that undo each other.Addition and Subtraction are
inverse operations
6 + 3 = 9 9 – 3 = 6

Identity Property
Any number plus zero equals that same number.
6 + 0 = 6 24 + 0 = 24
![Page 14: ADDITION VOCABULARY and PROPERTIES T. GOODSON JME](https://reader035.vdocuments.net/reader035/viewer/2022062322/5697c00a1a28abf838cc7734/html5/thumbnails/14.jpg)
Commutative Property of
Addition
When you add two numbers in any order you reach the same sum.
6+3=9 & 3+6=9
![Page 15: ADDITION VOCABULARY and PROPERTIES T. GOODSON JME](https://reader035.vdocuments.net/reader035/viewer/2022062322/5697c00a1a28abf838cc7734/html5/thumbnails/15.jpg)
Associative Property of
Addition
When you add three or more addends in different ways, the sum stays the same.
6+3+4=13 3+4+6=13 4+6+3=13 6+4+3=13 3+6+4=13 4+3+6=13
![Page 16: ADDITION VOCABULARY and PROPERTIES T. GOODSON JME](https://reader035.vdocuments.net/reader035/viewer/2022062322/5697c00a1a28abf838cc7734/html5/thumbnails/16.jpg)
It does not matter what

6… Their sum will always be
13.
