Explain how to use properties of addition

When we add two or more whole numbers, their sum is the same regardless of the order of the addends. The sum of both 2 + 4 and 4 + 2 is 6. That means, we can add whole numbers in any order. When three or more numbers are added, the sum is the same regardless of the grouping of the addends.

The 4 main properties of addition are commutative, associative, distributive, and additive identity. Commutative refers that the result obtained from addition is still the same if the order changes. Associative property denotes that the pattern of summing up 3 numbers does not influence the result.

Hope this helps :)

a) 9 + 3 = 12

b) 5x = (5 x 6 = 30) 30

c) 2x (2 x 3 = 6) = 13

d) 5x (5 x 2 = 10) = 14 + x (10)

I hope it is right
