Evaluate each expression using properties of numbers. Name the property used in each step.
$18 + 41 + 32 + 9$

Short Answer

Expert verified

The value of the given expression is $100$ .

Step by step solution

01

Step 1. Commutative property of addition.

If $a$ and $b$ two integers then $a + b = b + a$

02

Step 2. Application of commutative property of addition.

$18 + 41 + 32 + 9 = 18 + 32 + 41 + 9 [By commutative law of addition] = (18 + 32) + (41 + 9) = 50 + 50 [Substitution]$

03

Step 3. Simplifying the expression.

$50 + 50 = 100 [Substitution]$
