Capitolo 1, Problema 77
State the name of the property illustrated. 6+(2+7)=(6+2)+7
Guida verificata passo dopo passo1
Identify the expression given: \(6 + (2 + 7) = (6 + 2) + 7\).
Notice that the numbers and the operation (addition) remain the same on both sides of the equation; only the grouping of the numbers changes.
Recall that the property which allows you to change the grouping of numbers in addition without changing the result is called the Associative Property of Addition.
The Associative Property of Addition states that for any numbers \(a\), \(b\), and \(c\), the equation \(a + (b + c) = (a + b) + c\) holds true.
Therefore, the given equation illustrates the Associative Property of Addition.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Associative Property of Addition
The associative property of addition states that when adding three or more numbers, the way in which the numbers are grouped does not affect the sum. For example, (a + b) + c = a + (b + c). This property allows us to change the grouping of addends without changing the result.
