In mathematics, a binary operation is commutative if you change the order of the operands does not affect the final result. This is a fundamental property of many binary operations, and depend on many mathematical proofs. The commutativity of simple operations such as multiplication and addition of numbers, it was assumed implicitly for many years and the house is not mentioned until the 19th century, when mathematics started to be developed. By contrast, division and subtraction is not commutative.
Indeed, in the commutative property, we can see the journey that the exchange word from the Latin word meaning commutare
The exchange of words in turn can mean switch. For example, wash my face and combed my hair is a good example of this object.
Another good example of doing my math homework and reading after finishing my science.
The most important consideration in the above two examples is that the order of doing things can be changed so that no matter or cause no problems or conflicts.
However, reading a math lesson and then answer the review questions is not interchangeable.
This is the sequence does not matter because I have to give a lecture before knowing how the review questions
Math can be a two way street! In this BrainPOP movie, Tim and Moby introduce you to the commutative property. You will discover what the commutative property, that the activities of the commutative property applies to, and why change the numbers around does not always make the difference. Find out what order you have to do with it, and how they sound very smart to explain commutative. (Hint: Say it with letters instead of numbers)
