b) associative over addition
c) Associative over multiplication
d) commitive

Answer 1

b) associative over addition

Step-by-step explanation:

Associative property of addition states that the sum of two or more numbers is the same regardless of how we group the numbers.

For example, we may group the numbers 3, 4 and 5 in two different ways:

--> (3 + 4) + 5 = 7 + 5 = 12

--> 3 + (4 + 5) = 3 + 9 = 12
