Answer: 4. Commutative postulate for addition
Step-by-step explanation:
The commutative postulate for addition says that for any real number a and b
a+b=b+a
It tells that order doesn't matter if we add two numbers , the answer will remain same
The given expression is [tex]3 + 2 = 2 + 3[/tex], where 3 and 2 are real numbers.
Since
[tex]3 + 2 =5\\2 + 3=5[/tex]
Therefore, [tex]3 + 2 = 2 + 3[/tex] by Commutative postulate for addition.
