Lesson Steps
Step | Type | Explanation | Answer |
---|---|---|---|
1 |
Problem |
What is the commutative property of addition of x and y if x is equal to 25 and y is equal to 37? |
|
2 |
Step |
Given that |
x = 25 |
3 |
Step |
Substitute the given values into the expression x + y and evaluate |
x + y = 25 + 37 |
4 |
Step |
Perform the addition operation |
x + y = 62 |
5 |
Step |
Substitute the given values into the expression y + x and evaluate |
y + x = 37 + 25 |
6 |
Step |
Perform the addition operation |
y + x = 62 |
7 |
Step |
Since both expressions yield the same result of 62, we confirm that the commutative property of addition holds true for x = 25 and y = 37. |
|
8 |
Choice.A |
This answer is incorrect because by applying the commutative property of addition we got the result as 62, not 26 |
26 |
9 |
Choice.B |
Adding 25 and 37 equals 62, the same as 37 plus 25, making B the correct choice |
62 |
10 |
Choice.C |
The commutative property ensures adding numbers in any order yields the same sum; thus, the result should remain positive, not negative |
-26 |
11 |
Choice.D |
Incorrect due to failure to reflect addition’s commutative property; changing sign alters value, violating property |
-62 |
12 |
Answer |
Option |
B |
