Commutative Property - 1st Grade Math Worksheet Catholic ... - Free Printable

Problem Explanation:

The task involves using the commutative property of addition to solve the given problems. The commutative property states that the order of numbers in an addition operation does not affect the sum. Mathematically, this is expressed as:

\[
a + b = b + a
\]

For each problem, we need to:
1. Find the sum of the given numbers.
2. Use the commutative property to write an equivalent expression by swapping the order of the numbers.

Step-by-Step Solution:

#### 1. \( 7 + 5 \)
- Sum: \( 7 + 5 = 12 \)
- Equivalent Expression (using commutative property): \( 5 + 7 \)

#### 2. \( 2 + 4 \)
- Sum: \( 2 + 4 = 6 \)
- Equivalent Expression (using commutative property): \( 4 + 2 \)

#### 3. \( 6 + 3 \)
- Sum: \( 6 + 3 = 9 \)
- Equivalent Expression (using commutative property): \( 3 + 6 \)

#### 4. \( 7 + 9 \)
- Sum: \( 7 + 9 = 16 \)
- Equivalent Expression (using commutative property): \( 9 + 7 \)

#### 5. \( 10 + 0 \)
- Sum: \( 10 + 0 = 10 \)
- Equivalent Expression (using commutative property): \( 0 + 10 \)
