Q. Which equation shows the commutative property of addition?Choices:(A) s=s+0(B) t+s=s+t(C) s+t=u+v(D) s+(t+u)=(s+t)+u
Understand Commutative Property: Understand the commutative property of addition. The commutative property of addition states that the order in which two numbers are added does not change the sum. In other words, a+b=b+a.
Analyze Answer Choices: Analyze each answer choice to see which one demonstrates the commutative property.(A) s=s+0 does not show the commutative property; it shows the identity property of addition.(B) t+s=s+t directly shows the commutative property, as it indicates that the sum remains the same regardless of the order of the addends.(C) s+t=u+v does not necessarily show the commutative property, as it does not relate the same addends in a reversed order.(D) s+(t+u)=(s+t)+u shows the associative property of addition, not the commutative property.
Select Correct Answer: Select the correct answer based on the analysis.The correct answer is (B) t+s=s+t because it is the only choice that directly demonstrates the commutative property of addition.
