Q. Which property of addition is shown?(s+t)+u=s+(t+u)Choices:(A)associative(B)commutative(C)identity
Understand Associative Property: Understand the associative property of addition. The associative property of addition states that the way in which addends are grouped does not change the sum. In mathematical terms, this property is expressed as (a+b)+c=a+(b+c).
Compare with Property: Compare the given equation with the associative property.The given equation is s + t) + u = s + (t + u)\. This matches the form of the associative property of addition, where the grouping of addends is changed but the sum remains the same.
Identify Property Shown: Identify the property of addition shown by the given equation.\(\newlineSince the given equation matches the form of the associative property of addition, we can conclude that the property being shown is the associative property.
