The associative property allows you to group numbers differently when performing addition.
Starting with the expression \((50 + 30) + 40\), we can use the associative property to regroup the numbers. One possible way to rewrite this using the associative property is:
\[ 50 + (30 + 40) \]
Now, we can simplify the expression:
-
Calculate \(30 + 40\): \[ 30 + 40 = 70 \]
-
Now substitute this back into the expression: \[ 50 + 70 \]
-
Finally, add \(50 + 70\): \[ 50 + 70 = 120 \]
So, the expression \((50 + 30) + 40\) rewritten using the associative property and correctly simplified results in \(120\).
