addition
Addition satisfies two important properties: the commutative property and the associative property. The commutative property says that

symbol spacea + b = b + a

for all a and b. For example,

symbol space3 + 2 = 2 + 3

The associative property says that

symbol space(a + b) + c = a + (b + c)

for all a, b, and c. For example,

symbol space(1 + 2) + 3 = 1 + (2 + 3)
