Chapter R.15, Problem 1DE

To determine

To calculate: The expression equivalent to the algebraic expression $w+3$ by the use of commutative law.

Answer to Problem 1DE

Solution:

The expression equivalent to the algebraic expression $w+3$ is $\underset{\_}{3+w}$.

Explanation of Solution

Given information:

The provided expression is $w+3$.

Formula used:

The commutative law of addition states that, for any number a and b the order of addition does not affect the answer, that is:

$a+b=b+a$

Calculation:

Consider the expression as below:

$w+3$

Apply, commutative law of addition,

Then the expression $w+3$ is also written as below:

$w+3=3+w$

Hence, the expression equivalent to the algebraic expression $w+3$ by the use of commutative law is $3+w$.
