Q. Which property of addition is shown?(r+s)+t=r+(s+t)Choices:(A)associative(B)commutative(C)identity
Understand Addition Properties: Understand the properties of addition. The associative property of addition states that the way in which numbers are grouped does not change their sum. This property is written as (a+b)+c=a+(b+c). The commutative property of addition states that the order in which two numbers are added does not change their sum. This property is written as a+b=b+a. The identity property of addition states that any number plus zero is the number itself. This property is written as a+0=a.
Compare with Properties: Compare the given equation with the properties of addition.The given equation is r + s) + t = r + (s + t)\. We need to determine which property of addition this equation represents.
Identify Property: Identify the property shown by the given equation.\(\newlineThe given equation, \(r + s) + t = r + (s + t)\, matches the format of the associative property of addition, which is \(a + b) + c = a + (b + c)\. This shows that the sum remains the same regardless of how the addends are grouped.
