Question

The sum (267 + 345) + 21 is same as the sum 267 + (345 + 21).

• A. True
• B. False

Answer 1

The correct option is A

True

Associative Property states: When three or more numbers are added, the sum is the same regardless of the order of addition. The property states 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.
