Use the Associative Property of Addition to find the total of 4, 12, and 18 in two different ways.
(4+12) +18 = 16 + 18 = 34: (12 + 4) + 18 = 16 + 18 = 34
4+12 + 18 = 16 + 18 = 34; 18 + 12 + 4 = 30 + 4 = 34 (4 + 12) + 18 = 16 + 18 = 34; 4 + (12 + 18) = 4 + 30 = 34
4+12+18 = 16 + 18 = 34; 12 + 18 + 4 = 30 + 4 = 34
(4+12) +18 = 16 + 18 = 34: (12 + 4) + 18 = 16 + 18 = 34
Using the Associative Property of Addition, we can find the total of 4, 12, and 18 in two different ways.
First way:
(4 + 12) + 18 = 16 + 18 = 34
Second way:
(12 + 4) + 18 = 16 + 18 = 34
So, the total of 4, 12, and 18 is 34.
To use the Associative Property of Addition, we can group the numbers differently but still get the same total.
In the first way, we can add 4 and 12 first: (4 + 12) + 18 = 16 + 18 = 34.
In the second way, we can add 12 and 18 first: 4 + (12 + 18) = 4 + 30 = 34.
Both ways give us the same total of 34. This demonstrates the Associative Property of Addition, which states that when adding three or more numbers, it doesn't matter how you group them.
