WebThe commutative property is applicable to multiplication and addition. For Addition: The Commutative law for addition is expressed as A + B = B + A. For example, (7 + 4) = (4 + 7) = 11. This shows that even after we change the order of the numbers, 7 and 4, the sum remains the same. WebProblem 1: Rotate arrays 90 degrees. Problem 2: Interpreting rows and columns in rotated arrays.

WebThe commutative law means you can do the problem with the digits in any order, eg. 1+4+9 or 4+9+1 or 9+1+4. No matter how you order the numbers, you are still going to get the same answer (14). The associative law means to change the order of the digits but show that you still have the same answer, eg. (6+7)+2= (7+2)+6. Both ways equal 15.
