Question

evaluate the expression using properties of numbers. name the property used in each step. 25 + 14 + 15 + 36 = 25 + 15 + 14 + 36 associative property (+) = (25 + 15) + (14 + 36) commutative property (+) = 40 + 50 associative property (+) = 90 associative property (+)

Explanation:

Step1: Rearrange terms

$25 + 14+15 + 36=25 + 15+14 + 36$ (Commutative Property of Addition)

Step2: Group terms

$=(25 + 15)+(14 + 36)$ (Associative Property of Addition)

Step3: Calculate grouped sums

$=40 + 50$

Step4: Find final sum

$=90$

Answer:

90
