6 × 4 = 4 × 6, Are they the same?


The result of 6 × 4 and 4 × 6 is the same, that is 24. But they have the different logic. The situation of  6 × 4 and 4 × 6 is not same.

 For example:
John and David have to move 24 box. John more strong than David, so that John able to bring 6 box for 4 times. In mathematics is 4 × 6.




But, David just bring  4 box for 6 times. In mathematics is 6 × 4.

John more than fast than David because he can move 24 box in 4 times but David need 6 times to move 24 box.
So, 6 × 4 = 4 × 6 because the result of 6 × 4  and  4 × 6 is the same.  But the concept of  6 × 4 = 4 + 4 + 4 + 4 + 4 + 4 is not same with 4 × 6 = 6 + 6 + 6 + 6.
Mathematics teach logic, it is not only about calculate number.
