The expression is 17 + 6 + 13 + 24.
\= 17 + 13 + 24 + 6 (Apply commutative property of addition: a + b = b + a)
\= (17 + 13) + (24 + 6) (Apply associative property of addition: (a + b) + c = a + (b + c))
\= 30 + 30 (Add: 17 + 13 = 30 and 24 + 6 = 30)
\= 60 (Add: 30 + 30 = 60) ![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The value of the expression is 60.
