<h2>Answer</h2>
Addition sentence: 3 + 5 + 6 = 14
First way to find the sum:
(3 + 5) + 6 = 14
8 + 6 = 14
14 = 14
Second way to find the sum:
3 + (5 + 6) = 14
3 + 11 = 14
14 = 14
<h2>Explanation </h2>An addition sentence is a mathematical expression in which we add tow or more numbers together.
We need to choose three numbers form 1 to 6, so our numbers will be 3, 5, and 6
Now to create our sentence we are add our three numbers together:
3 + 5 + 6
Since 3 + 5 + 6 =14, our addition sentence is 3 + 5 + 6 =14
Now, lets use the associate property of addition, to show to ways to add our addition sentence.
First way
We will associate 3 and 5 using a parenthesis; then we will add 3 and 5 inside the parenthesis, and last, we add the result to the number 6 outside the parenthesis:
(3 + 5) + 6 = 14
8 + 6 = 14
14 = 14
Second way
This time we will associate 5 and 6 using a parenthesis; then we will add 5 and 6 together, and last, we will add the result to the number 3 outside the parenthesis:
3 + (5 + 6) = 14
3 + 11 = 14
14 = 14
