They are useful in speeding up basic arithmetic calculations.
The properties allow you to rearrange the arguments of a calculation and the order in which the operations are carried out. So, for example,
(5 + 13) + 15 = (13 + 5) + 15 [using the commutative property]
= 13 + (5 + 15) [using the associative property]
= 13 + 20 = 33.

Both properties combined let you rearrange numbers, or variables, when adding several numbers or multiplying several numbers. This can often help solving equations.
