This document discusses properties of addition and multiplication. It defines the closure, commutative, and associative properties of both addition and multiplication. Examples are provided to illustrate each property, such as the sum or product remaining the same regardless of the order or grouping of numbers.

2. 1.Closure property of addition.
2.Commutative property of addition.
3.Associative property of addition.
4.Closure property of multiplication.
5. Commutative property of multiplication
6.Associative property of multiplication

3. The sum of any two whole numbers
will always be whole number
 Example:12+0=12

4. The commutative property of
addition says that changing the
order of addends does change the
sum
Example:4+2= 2+4

5. Associative property explains that
addition an multiplication of numbers
are possible regardless of how they
are grouped
Example: (2+3)+4=2+(3+4)

6. Closure property under
multiplication states that any two
rational numbers product will be a
rational
Example:2times -1 = -2

7. The commutative property is a math
rule that says that the order in which
we multiply number does not change
the product
Example:4times3=3times 4

8. The way in which factors are grouped in a
multiplication problem does not change the
product
Example:5times 4times 2
