How to use commutative and associative property to simplify 431+37+69+63 Please anwser fast

Commutative property:
Commutative property states that in which ever order you arrange your numbers, the result will be the same. But it supports only addition and multiplication.
Regroup the numbers like 431+69+37+63
Now when you add 431 and 69, you get 500.
When you add 37 and 63, you get 100.
When you add 500 and 100, you get 600 - your result.

Associative property:
It is again somewhat the same.
Here you take 1 number out and put the other 3 numbers inside the bracket.
37+(431+69+63)
If needed you can again group them as:
37+[63+(431+69)]
=37+[63+(500)]
=37+[63+500]
=37+563
=600
