Do you think using the commutative and associative properties made the sale
Here we used a combination of commutative and associative properties for addition
Here we used a combination of commutative and associative properties for multiplica
Example-
Find 196 +57 + 4
Solution:
196+ (57 + 4)
- 196 +(4+57) Commutative property]
-(196 + 4)+ 57 | Associative property]
- 200 + 57 = 257

Example-2. Find 3 * 9 * 2 * 2 * 3*5
Solution: 3 x 9 x 2 x 2 x 3 x 5
-5x 2 x 9 x 2 x 5 x 3
[Commutative property]
-(sx 2 x 9 x (2 x 5 x 3
[Associative property]
- 10 x 9 x 10 x 3

Answer 1

Answer:

In math, the associative and commutative properties are laws applied to addition and multiplication that always exist. The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.

Step-by-step explanation:

Find 196 +57 + 4

Solution:

196+ (57 + 4)

- 196 +(4+57) Commutative property]

-(196 + 4)+ 57 | Associative property]

- 200 + 57 = 257196 + 4)+ 57 | Associative property]

- 200 + 57 = 257
