use properties to find the sum or product

Use Commutative Property: a + b = b + a and Associative Property: (a + b) + c = a + (b + c)
34 + 0 + 18 +26 = (34 + 26) + 18 = 60 + 18 = 78

To find sums or products, use the Commutative Property, which states the order does not matter, and the Associative Property, which states that grouping does not affect the result. For example, summing 34, 0, 18, and 26 gives a total of 78, and multiplying 2, 3, and 4 gives 24. These properties allow for flexible rearrangement of numbers for easier calculations.
