Q. Which property of addition is shown?s+r=r+sChoices:(A) associative(B) commutative(C) identity
Identify Property of Addition: Identify the property of addition that involves changing the order of the addends without changing the sum.The commutative property of addition states that changing the order of the addends does not change the sum. It is expressed as a+b=b+a.
Compare Given Equation: Compare the given equation s+r=r+s with the properties of addition.The given equation matches the form of the commutative property of addition, where the addends s and r are swapped in order without affecting the sum.
Eliminate Other Choices: Eliminate the other choices based on the definition of each property.(A) Associative property involves the grouping of addends and is expressed as (a+b)+c=a+(b+c).(C) Identity property involves adding zero to a number and is expressed as a+0=a.Neither of these properties is demonstrated by the equation s+r=r+s.
Select Correct Property: Select the correct property of addition that is shown by the equation s+r=r+s.The correct property is the commutative property of addition.
