Answer: Option A. -> True
Associative Property states: When three or more numbers are added, the sum is the same regardless of the order ofaddition. Thepropertystates that for all real numbers a, b, and c, their sum is always the same, regardless of their grouping. (a+b)+c = a+ (b+c)
So(267 + 345) + 21 and 267 + (345 + 21)will give the same result = 633.
