com·mu·ta·tive property

(kə-myo͞o′tə-tĭv, kŏm′yə-tā′tĭv)
The property of addition and multiplication which states that a difference in the order in which numbers are added or multiplied will not change the result of the operation. For example, 2 + 3 gives the same sum as 3 + 2, and 2 × 3 gives the same product as 3 × 2. See also associative property, distributive property.
